765704054Life Cycle of a Blood Fluke1.) mature flukes live in blood vessels of human intestines 2.) flukes reproduce sexually in host. Fertilized eggs exit the host in feces 3.) If the human feces reach a pond or other source of water, the eggs develop into ciliated larvae. Larvae infect snails (intermediate snails) 4.) Asexual reproduction inside snail results in a motile larva, which escapes the snail host 5.) Larvae penetrate the skin and blood vessels of humans working in the water with contaminate fluke larvae

Terms : Hide Images
675291751Closest relatives to Land PlantsCharophytes- photosynthetic protist- a type of algae Ex: Chara & Coleochaete orbicularis0
6752917524 synapomorphies of land plants & charophytes1.) Rings of cellulose-synthesizing proteins 2.) Peroxisome enzymes 3.) Structures of flagellated sperm 4.) Formation of a phragmoplast1
675291753Rings of cellulose-synthesizing proteinsBoth my rings of proteins in the plasma membrane that synthesize cellulose microfibrils of the cell wall (non charophyte algae have linear proteins)2
675291754Peroxisome enzymesPeroxisomes of both types of organisms contain enzymes to help minimize the loss of organic products results from photorespiration3
675291755Structure of flagellated spermboth have sperm with similar structures4
675291756Formation of a phragmoplastPhragmoplast- a group of microtubules that forms between daughter nuceli of a dividing cell. A cell plate then develops in the middle of the phragmoplast--> cell plate gives rise to new wall that seperates daughter cells5
675346044Sporopolleninfound in charophytes - prevents exposed zygotes from drying out ; may have helped evolutionary transition to land6
6753460455 Synapomorphies found ONLY in land plants1.) Alternation of Generations ; 2.) Muticellular, Dependent Embryos ; 3.) Walled spores produced in sporangia; 4.) Multicellular Gametangia; 5.) Apical meristems - all are derived traits of land plants7
6753460461.) Alternation of Generationslife cycle of land plants alternates between gametophytes and sporophytes. Each generation gives rise to the other. - half the cycle is haploid (n) and half is diploid (2n)8
6753460475 steps of Alternation of Generation Life Cycle1.) The gametophyte produces haploid gametes (n) by mitosis 2.) 2 gametes unite(fertilization) to form a diploid (2n) zygote 3.) Zygote develops into multicellular diploid (2n) sporophyte 4.) Sporophyte produces haploid (n) spores by meiosis 5.) Spores develop into haploid gametophytes by mitosis- cycle begins again9
675346048Gametophyte- multicellular haploid that is produces, by mitosis, haploid gametes- egss & sperm- that fuse during fertilization, forming diploid zygotes10
675346049Sporophyte- multicellular diploid that is produced by mitotic division of the zygote Ex: in a fern, this is the large plant that we recognize11
6753460502.) Multicellular, Dependent Embryos-these embryos develop from zygotes retained in the female gametophyte. The parent tissue provides the embryo with nutrients such as sugars and a.a.'s - embryo has specialized placental transfer cells - this is analogous to the embryo-mother interface of placental mammals = hence land plants are called embryophytes12
675346051Placental transfer cells-sometimes present in adjacent maternal tissue as well - enhance the transfer of nutrients from parent to embryo through ingrowths of the wall surface13
6753460523.) Walled Spores Produced in Sporangia- On the sporophyte, the sporangia produce the spores - Within the sporangia, diploid cells produce sporocytes, or spore mother cells--> these will form haploid spores via meiosis - sporangium- protects developing spores until they are released into the air -spores also have sporopollenin that make spore walls tough and resistant to drying out14
6753460534.) Multicellular Gametangia-gametes are produced inside here. - there are male and female gametangia15
675346054Archegoniafemale gametangia - produces an egg retain the bulbous part of the organ -each egg is fertilized inside the the archegonium where the zygote becomes an embryo16
675346055Antheridiamale gametangia - produces sperm and releases them into the environment -sperm have flagella that swim to the egg in droplets of water17
6753460565.) Apical meristems-Roots and shoots of terrestrial plants elongate to increase exposure to resources (i.e. sunlight, water, minerals etc.) - apical meristems are regions of cell division at the tips of roots and shoots - growth in length of a plant's life is sustained by apical meristems18
675346057Cuticlewaxy covering on leaves to prevent dessication and water loss & protect against some microbial attack19
675346058Origin of Land Plants475 million years ago20
675346059Origin of Vascular plants425 million years ago21
675346060Origin of extant seed plants305 millions years ago22
675346061Vascular tissue in plantscell joined into tubes that transport water and nutrients thru out the plant body - plants that have this = vascular plants23
675346062Non-vascular plantslack vascular tissue commonly called bryophytes24
6753460633 types of Bryophytesliverworts, mosses, and hornworts - in bryophytes, haploid gametophytes are the dominant stage in the life cycle25
675346064Two types of Seedless Vascular plantsLycophytes (club mosses and their relatives) and pterophytes (ferns and their relatives)26
675346065Gradecollection of organisms that share a key biological feature - do not necessarily share the same ancestry Ex: Seedless vascular plants- are not part of clade, are actually paraphyletic27
675346066Seedembryo packaged with a supply of nutrients inside a protective coat28
675346067Two types of seed plantsgymnosperms and angiosperms29
675346068Gymnospermshave "naked" seeds - seeds are not enclosed in chambers30
675346069Angiosperms-huge clade of flowering plants - seeds develop inside chambers called ovaries, which mature into fruits -90% of living plants are angiosperms31
6753460703 Phylum of Bryophytes (non-vascular plants)1.) Hepatophyta - liverworts ; ex: Marchantia 2.) Bryophyta- mosses ; ex: "peat moss"- a.k.a Sphagnum 3.) Anthocerophyta- hornworts- their sporophytes lack a seta and only have a sporangium32
675404987Bryophyte gametophytes- the haploid gametophytes dominate their life cycle - germinating spores grow into gametophytes33
675404988Protonema- developed from germinating moss spores - one-cell thick filaments that has a large surface area for absorbing mineral & water absorbtion - in favorable conditions this protonema will produce a "bud" that has apical meristem that will generate a gametophore34
675404989Gametophoregamete-producing structure on the "bud" - gametophore together with a protonema make up a gametophyte35
675404990Why are bryophytes typically smaller than other plantss?their body parts are too thing to support a tall plant and they lack vascular tissue so do not have the ability to transport nutrients and water over long distances36
675404991Rhizoidsanchors the gametophytes - are long and tubular in liverworts & hornworts -filament of cells in mosses - similar to roots but do absorb water or minerals37
675404992Bryophyte Sporophytes- are the smallest of all extant plant groups - consists of a foot, a seta, and sporangium (a.k.a capsule) - most seta becomes elongate to enhance seed dispersal by elevating the sporangium - pores in them called stomata- water evaporates from this (only present in mosses and hornworts)38
675404993Life cycle of a moss- majority is haploid 1.) Haploid (n) spores develop into threadlike protonemata 2.) Protonemata produces "buds" that divide by mitosis and grow into gametophores --> which forms the male or female gametophytes (n) 3.) Gametophytes form archegonium and antheridia 4.) Sperm from antheridia swim through a film of moisture to reach the egg at the achegonium (fertilization)39
675404994Life cycle of a moss continued5.) Zygote (2n) forms inside archegonium and develops into a sporophyte embryo 6.) Sporophyte grows a long stalk (seta) that emerges from the archegonium 7.) The sporophyte remains attached by its foot and nutritionally dependent on the gametophyte 8.) Meiosis occurs and haploid (n) spores develop in the capsule (or sporangium) until it matures and then the spores are released and cycle repeats40
675416491Seedless Vascular Plants- had well developed vascular systems by the Devonian era - has flagellated sperm that must swim through water to reach the egg, like bryophytes41
675416492Traits of ancestral vascular plants- branched sporophytes that were not dependent on gametophytes for nutrition - made it possible to have more complex bodies with multiple sporangia - lacked roots ex: Aglaophyton major- an ancient relative or modern vascular plants42
675416493Traits in living vascular plants1.) life cycles with dominant sporophytes 2.) transport in vascular tissue 3.) well-developed roots and leaves, including spore-bearing leaves called sporophylls43
675416494Life Cycle of a Fern1.) Sporangia release spores (n). Ferns produce a single type of spore that develops into a bisexual photosynthetic gameteophyte 2.) each gametophyte develops both a sperm-producing antheridium and and egg-producing archegoniums 3.) Flagellated- sperm swim to eggs in archegonia (fertilization)44
675416495Life Cycle of a Fern part 24.) A zygote (2n) develops into a new sporophyte. The young plant grows out from an archegonium of its parent, the gametophyte 5.) on underside of mature sporophytes' reproductive leaves are spots called sori- cluster of sporangia 6.) sporangia undergoes meiosis and will release its haploid spores(n)- cycle begins again.45
675416496Two types of vascular tissuexylem & phloem46
675416497Xylem-moves water and minerals through the vascular tissue - in most plants this includes tracheids- tube shaped cells that carry water and minerals up from the roots47
675416498Phloem- tubes that distribute sugars, a.a.'s, and other organic products48
675416499Roots-absorb water and nutrients from the soil - help to anchor vascular plants49
675428140Leavesincrease the SA of the plant body and act as the primary photosynthetic organ of vascular plants - classified as either micro- or mega- phylls50
675428141Microphylls-only lycophytes have these - small spine-shaped leaves supported by a single strand of vascular tissue - may have evolved from sporangia located on the side of the stem51
675428142Megaphylls- leaves with highly branched vascular system - may have evolved by the fusion of branched stems52
675428143Sporophyllsmodified leaves that bear sporangia - vary in structure53
675428144Soriculsters of sporangia produced by fern sporophylls54
675428145Strobilicone-like structures formed from lychophyte and gymnosperm sporophylls55
675428146Homosporousone type of sporangium that produces one type of spore --> forms a bisexual gametoophyte, like in ferns56
675428147Heterosporoushas two types of sporangia and produce two kinds of spores: megaspores or microspores57
675428148Megaspores- produced by megasporangia on megasporophylls - develop into female gametophytes58
675428149Microspores- produced by microsporangia on microsporophylls - develop into male gametophytes59
6756354512 Clades of Seedless Vascular PlantsLycophytes (Phylum Lycophyta) & Pterophytes (Phylum Pterophyta)60
675635452LycophytesClub mosses, Spike Mosses and Quillworts - most ancient group of vascular plants - were prevalent during Carboniferous period (359-299 mya ; had large lycophyte trees 40m tall near swamps but died out when Earth's climate dried out61
675635453PterophytesFerns, Horsetails, and Whisk Ferns - ferns radiated outward from the Devonian and joined lycophyte trees and horsetails in the Carboniferous period - ferns are the most widespread seedless vascular plant62
675635454Shared traits Between Pterophytes and seed plants- pterophytes are more closely related to see plants than lycophytes -both have overtopping growth, megaphyll leaves, and branching roots at various points along existing root - in contrast, lycophyte roots only branch at tip of the root forming a Y shape63
675635455Lycophyte Characteristics- many grow on tropical trees as epiphytes ; others on forest floors - spike/club mosses have strobili = cluster of sporophylls - club mosses are homosporous - spike mosses and quill worts are heterosporous - club mosses release spores in cloud= once used to ignite and create a flash in old photography Ex: Lycopodium64
675635456Epiphytesplants that use other plants as a substrate but are not parasites65
675635457Ferns- have megaphylls - sporophytes have horizontal stems that give rise to fronds, divided into leaflets - most are homosporous - most have sporopytes with stalked sporangia to catapult spores several meters66
675635458Horsetailsex: Equistem arvense - historically used as "scouring rushes" due to bristly appearance - homosporous, have cones that release spores that give rise to bisexual gametophytes -also called arthrophytes "Jointed plants" b/c the stems have joints67
675635459Whisk Ferns-sporophytes have dichotymously branching stems, but no roots - each yellow knob on a stem is 3 fused sporangium -homosporous, with spores giving rise to bisexual gametophytes Ex:Psilotum nudum68
675635460How did Seedless Vascular Plants affect life on Earth during the Devonian/ Carboniferous periods?- plants accelerated rate of photosynthesis -> increasing removal of CO2 from atmosphere (CO2 levels dropped 5 fold during this time) --> this caused global cooling and glacier formation69

673476698Example of Convergent evolutionAustralian "mole", a marsupial = young complete embryonic development in an external pouch, looks similar to the North American mole, a eutherian = young complete embryonic development in the uterus
673476699Example of an AnalogyIn respect to flight, a bat's wing is analogous to a bird's wing
673476700Homoplasiesanalogous structures that arose independently
673476701Molecular Systematicsdiscipline that used data from DNA and other molecules to determine evolutionary relationships
673476702Monophyletic groupa clade; consists of an ancestral species and all of its descendents; ideal grouping
673476703Paraphyletic groupConsists of an ancestral species and some of its descendants but not all of them ; incomplete group, most groups are this
673476704Polyphyletic groupsome of its members have different ancestors
673476705Shared ancestral characteristicscharacter that originated in an ancestor of the taxon ex: for mammals, the backbone is one b/c it was present in the ancestor common to all mammals.
673476706Shared derived characteristicsan evolutionary novelty unique to a clade ex: for mammal, hair is one. Hair is a characteristic shared by all mammals but is not found in their ancestors
674429430Outgroupspecies or group of species from an evolutionary lineage that is known to have diverged before the lineage that includes the species we are studying
674429431Ingroupthe species or group of species we are studying
674429432Amniotic egg- most important point in vertebrae evolution - separate from parent with shell around it & various tissues inside shell - can give developing embryo nutrients & takes away metabolic wastes
674429433Maximum parsimonya.k.a. "Occam's razor" - simplest route is probably the way that an event occurred - most parsiminous route = has least # of mutations or the fewest evolutionary events
674429434Closest living relative to birdsCrocodile
674429435Actual closest relative to birdsTheropod saurischian dinosaurs
674429436Two types of homologous genesorthologous and paralogous
674429437Orthologous genesfound in different species ; their divergence traces back to the speciation events that produced the species ; divergence takes place after genes are found in separate gene pools ex: cyctochrome c genes in humans and dogs
674429438Paralogous genesresults from gene duplication; multiple copies of the genes have diverged from one another within a species Ex: genes that make up olfactory receptor gene family in humans
674429439Molecular clocka yardstick for measuring the absolute time of evolutionary change based on the observation that some genes and other regions of genomes appear to evolve at constant rates
674429440Horizontal gene transfergenes are transferred from one genome to another through mechanisms such as exchange of transposable elements and plasmids, viral infections, etc. -prokaryotes/ bacteria do this - passing genes back & forth between prokaryotes
674429441Ring of Life Theorytheory that eukaryotes are simultaneously most closely related to bacteria and archaea- forming a ring shaped evolutionary relationship
