4404379864fungi is more related to...animals than either is related to plants or charophyte algae0
4404386161What is the sister taxon to animals?taxon1
4404386162what is true of fungi and animals that is not true of plantsthey are heterotrophic2
4404401110alimentary canalis the tube that goes from mouth to anus(food does not go into the body it goes through it)3
4404406100How do we get nutrients from the food?secret enzymes into the alimentary canal to breakdown the molecules of the food then absorb them4
4404407947How does a fungus get food?it grows by adding cells onto the surface of whatever it eats5
4404431288what do plants and charophyte algae make cellulose with?circular arrangements of protein molecules6
4404439776what does it mean to be a sexual species?to undergo fertilization and meiosis7
4404442987fertilizationunion of 2 gametes to produce a zygote8
4404445710what does fertilization cause?doubling of the ploidy9
4404503777What does meiosis do?halves the ploidy10
4410348254in any sexual species there isa haploid and diploid part of the cycle11
4410349460What are the 3 major sexual groups?animals, plants, and fungi12
4410353857plants under what in regards to their sexual life cyclealternation of generations13
4410353858alternation of generationsboth the haploid and diploid stage are multicellular14
4410356091what do humans undergo?humans are diploid individual we then produce gametes by meiosis each of which is a single cell then forms a zygote which is now diploid.15
4410357905what do fungi undergo?its body is haploid and produces gametes by mitosis, the gametes produce a zygote by meiosis to produce haploid cell16
4410362795What part of the life cycle is multicellular for humans?diploid17
4410363222What part of the life cycle is multicellular for fungi?haploid18
4410364240What part of the life cycle is multicellular for plants?multicellular haploid and diploid stage19
4410364768what is the multicellular haploid stage in plants called?gametophyte stage and produces them by mitosis20
4410365379what is the multicellular diploid stage in plants called?sporophyte stage spores produced by meiosis which is now haploid which then can undergo mitosis to become multicellular gametophytes.21
4410373447nonvascular plants arethe basal taxon of plants which include moss, liverworts, and hornwarts22
4410379787what is life?the chemical reactions of aqueous solutions that we call metabolism23
4410381342sporangia isspore producing sacks that are encased by a wall which has sporopollenin inside of it24
4410382790sporopollenin causes sporangia to bewater proof and helps against desiccation25
4410388652Why were the first plants small?being multicellular is too complicated26
4410391186we could not have a cell as big as a human?The surface area to volume ratio the volume gets bigger faster than the surface area does.27
4410402690since surface doesn't grow as fast as volumeyou wont have enough surface area to absorb all the nutrients needed by the volume28
4410405664where does diffusion occur well?over short distances so the early small plants29
4410406873Why are humans able to be this bigin addition to diffusion we have convection which is the bulk movement of a fluid which is our blood and our heart is the convection. we have vessels30
4410409316why were early plants called nonvascularearly plants did not have vessels to export wastes they only had diffusion31
4410416505fungus islittle filaments called hyphae making up a mycelium32
4410419007mycelium iscollection of all the hyphae in a fungus, grows into and on whatever the substrate it uses as food.33
4410423127how do you know when a fungus is ready to reproduce?it has a fruiting body ie mushroom34
4410427874what is the purpose of hyphae?maximize surface area contact with the food that they are growing on.35
4410429371what is the symbiotic relationship between fungi and plants?the fungi will grow on the roots and help uptake nutrients in the environment36
4410434873Describe how fungi and plants help each otherthe fungi poke through the cell wall and the plasma membrane wraps around the fungi37
4410439697in fungi fertilization is in 2 eventsplasmogamy and karyogamy38
4410439698plasmogamyunion of cells and their cytoplasm as merged and their nuclei are individual39
4410441531what does plasmogamy give rise to?heterokaryotic40
4410445304heterokaryotichaving different nuclei41
4410447012karyogamycoming together of the nuclei to make a diploid zygote which will then undergo meiosis which produces haploid that grow up to be adult multicellular haploid fungi42
4410451425What is the basal taxon of fungichytrids that are unicellular fungi43
4410453281what do you use to describe a unicellular fungus?yeast44
4410455234myc or myco refers tofungus45
4410455243what does a mycologist study?fungi46
4410456528glomeromycetesglob like fungi47
4410457248what are the biggest fungi and the most abundantascomycetes and basidiomycetes48
4410460961major sub groups of plantsnonvascular plants(bryophytes) and vascular plants49
4410461878Why is it good for plants to become big?the taller you can become the more sunlight you can get50
4410467823vascular plants are divided into 2 sub groupsseedless vascular plants and seeded vascular plants51
4410468294seedless vascular plantsferns can get huge but do not produce seeds52
4410471194seeded vascular plants allowedseed containing an embryo with its own food supply53
44104735822 types of seeded plants?gymnosperms and angiosperms54
4410478434What type of plant produces flowersangiosperms55
4410486163In bryophytes (gametophyte and sporophyte)the gametophyte is the dominant stage so the sporophyte relies on it56
4410488864in seedless vascular plants (gametophyte and sporophyte)the sporophyte has dominance and is bigger over the gametophyte stage57
4410490328In seeded plants (gametophyte and sporophyte)the sporophyte has dominance and is bigger over the gametophyte stage you see the sporophyte of maple trees58
4410493470What does a seed start out as?a unfertilized ovule which is enclosed by its own chamber a pollin grain will come in and fertilization comes in and makes a zygote once it undergoes mitosis59
4410497002what is a seed?a growing embryo with its own food supple in its own case60
4410500431What type of tree is a conifergymnosperm61
4410502553What does a complete flower consist ofsepals, petals, stamens, and carpels62
4410507540Why are flowers vibrant colors?to advertise to pollinators which are insects mostly63
4410511290anther is wherepollen grains which contain male gametes are produced64
4410519075Lichens aresymbiotic relationship between a fungus and alga and are found on rocks which are important on producing soil by degrading rocks65
4410525514endophytea fungus that lives inside a plant that is a symbiotic relationship66
4410534084what does a bilaterally symmetrical flower mean?a pollinator does not have that many ways to get pollen which causes less gene flow.67
