Terms : Hide Images
Multicellular eukaryotes that have cell walls made of cellulose. develop from multicellular embryos and carry out photosynthesis.
diploid (2N) spore producing phase of a plants life-cycle., diploid, or spore-producing, phase of an organism
haploid (N) gamete producing phase of a plants life-cycle, the gamete-producing individual or phase in the life cycle of a plant having alternation of generations
Sunlight, water and minerals, gas exchange, movement of water and nutrients
The first plants evolved from an organism much like multicellular green algae.
algae(protist)--> moss,(water conducting vascular tissue) --> ferns,(seeds)--> cone bearing plants, --> angiosperms (flowering seeds enclosed in fruit) flowering plants
Mosses, Ferns, Gymnosperms(conifers), Angiosperms(flowering plants)
A moss, liverwort, or hornwort; a nonvascular plant that inhabits the land but lacks many of the terrestrial adaptations of vascular plants. Depends on water for reproduction
mosses, liverworts, hornworts
have rhizoids instead of roots; fuzzy green gametophyte; long slender sporophyte. Nonvascular
the hairlike fibers that anchor a moss to the soil and take in water from the soil
grows as a thick crust on moist rocks or soil along sides of streams. Small umbrella shaped structures for gametophyte stage.
small multicellular reproductive structures that allow liverworts to reproduce asexually
slender curved structures that look like horns; live in moist soil and often mixed with grass plants
sporophytes which produce haploid spores grow at the op of the gameotophyte plant, when the spores are ripe they are shed from the capsule the attach to a female gametophyte and make a new plant
mass of tangled green filaments in mosses that forms during germination
Location of sperm production in bryophytes. at the top of gametophytes
Location of egg production in bryophytes. at the top of gametophytes
tissue that conducts water and nutrients through the plant body by xylem and phloem
Specialized cells to conduct water, key cells in xylem.
the vascular tissue through which water and nutrients move in some plants
the vascular tissue through which food moves in some plants
substance in vascular plants that makes cell walls rigid and allows them to grow tall
underground organs that absorb water and minerals
The main photosynthetic organs of vascular plants that contain vascular bundles
carry substances between roots and leaves; provide support for plant; holds leaves up to sunlight
bundles of vascular tissue
look like tiny pine trees, grow in moist woodlands and nearby streams
seedless vascular plant with jointed stems; needlelike branches
underground stems; leaves are called fronds; most common nonvascular plant
underground stems of ferns
leaves of a fern
multicellular organs that produce spores in vascular plants. found on bottom of fronds in ferns
a group of sporangia
in this plant, diploid sporophyte is dominant phase
seed plant that bears its seeds directly on the surfaces of cones
A flowering plant, which forms seeds inside a protective chamber called an ovary then inside a fruit
the seed bearing structures of gymnosperms
the seed bearing structures of angiosperms
male gametophyte in seed plants
the transfer of pollen from male reproductive structures to female reproductive structures in plants
the embryo of a plant that is encased in a protective covering and surrounded by a food supply
an organism in its early stages of development (diploid)
protective outer layer of seeds of flowering plants
The reproductive structures unique to angiosperms
a wall of tissue surrounding a seed. not a leaf (attracts pollinators)
have one seed leaf (cotyledons)
has two seed leafs (cotyledons)
first leaf or first pair of leaves produced by the embryo of a seed plant
a flowering plant that completes its entire life cycle within the space of a year
flowering plant that completes its entire life cycle in two years
A plant lasting for three seasons or more
