10 Cards in this Set
- Front
- Back
|
Have chlorophylls a and b and carotenoids. May be unicellular or multicellular.
The embryos of these are unicellular. |
Chlorophytes. (Spirogyna and chlymadonas)
|
|
|
Do not have adequate water, means of water transport, or means of support. Need moist habitats to thrive. Lack tracheids.
|
Nontracheophyte plants. (Moss, Marchantia)
|
|
|
The haploid gametophyte generation is more prominent than the diploid sporophyte generation of these plants.
They have a sporophyte, a stalk topped with a capsule full of spores, which grows from the gametophyte. It is very leafy. |
Nontracheophyte plants. (Moss, Marchantia)
|
|
|
Well adapted for terrestrial habitat. They have transport systems to carry water from the soil to all parts of the plants. Can grow very tall.
|
Tracheophyte plants.
|
|
|
Have roots, stems, and leaves, and a vascular system to provide transport. Have only 1 unbranched vein. Has a prominent sporophyte produce a club-shaped strobilus at the top of the plant that produces spores.
|
Lycophytes (type of tracheophytes). Selaginella.
|
|
|
Have openings in the stem, called leaf gaps, where leaves emerge.
|
Monilophytes(fern-like plants) of tracheophyte plants. Equisetum and Ferns.
|
|
|
Are a type of monilophytes that have true stems, leaves, roots and a vascular system. The tissues of these plants contain silica that gives them a rough texture.
|
Equisetum(horsetails) of monilophytes plants
|
|
|
Very well developed vascular systems, Reproduce by structures called sori that produce spores that become the gametophyte. The sperm produced in the gametophyte must swim from the antheridia where they are produced to the archegonia, which house the eggs.
|
Ferns(of the monilophytes plants).
|
|
|
Produces seeds, pine cones. Male cones produce spores by meiosis that become pollen, which develop into male gametophytes that fertilize eggs in female cones.
|
Gynosperms(tracheophyte plants). Cycad, Ginkgo, and Norfolk Pine.
|
|
|
Flowering plants with seeds, with xylem vessels in addition to tracheids to convey water and minerals from the roots to the rest of the plants. Seeds are enclosed in fruits.
|
Angiosperms(tracheophyte plants).
|
