How are ferns different from other plants?
Ferns are plants that do not have flowers. Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.
How do ferns and mosses multiply?
Ferns and mosses reproduce by releasing millions of spores through the air. The spores are fed eggs and are spread through the environment by wind.
What do ferns have that mosses lack?
moss don’t have vascular tissue, ferns do. Also, what do ferns have that mosses lack? Mosses lack true roots, stems, and leaves. Ferns have roots, stems, and leaves and reproduce by spores.
What advantage do gymnosperms have over ferns?
What advantage did gymnosperms have over ferns? Gymnosperms produce pollen and do not require water to reproduce. Both seed protection and seed dispersal are correct.
Do plants go through mitosis or meiosis?
In plants, there’s a little break between meiosis and the production of sperm and eggs. During that break, a separate little haploid plant grows. Gametophytes produce gametes by mitosis. In animals, meiosis produces sperm and egg, but in plants, meiosis occurs to produce the gametophyte.
Are ferns Homosporous or Heterosporous?
Ferns are mostly homosporous, though some are heterosporous. The heterosporous state is a more advanced condition, that seems to have evolved independently in several groups of plants. The haploid spores are formed by meiosis inside the sporangium.
How do you tell if a plant is Homosporous or Heterosporous?
A main difference between homosporous and heterosporous pteridophytes is that homosporous pteridophytes produce only one type of spores, which are small in size while heterosporous pteridophytes produce two types of spores; the small microspores and the large megaspores.
Which is not a Heterosporus Fern?
Of all the options given in the question Selaginella, Pinus and Cycas all produce micorspores and megaspores for reproduction. However, Pteridium on the other hand is homosporous.
