Are all ferns Heterosporous?
No, ferns are not heterosporous; they are homosporous. This means that fern will produce spores that are of the same size and shape with no…
Are mosses and ferns Heterosporous?
Mosses are heterosporous, which means they make two distinct types of spores; these develop into male and female gametophytes. Ferns follow a pattern of development similar to that of mosses, although most (but not all) ferns are homosporous.
What plants are Homosporous?
Extant homosporous plants include most ferns and many lycophytes. The homosporous life cycle is an effective means for long-distance dispersal of species.
Are most terrestrial ferns Homosporous?
Gametophytes of homosporous plants may be bisexual, with both male and female gametangia, as in ferns, or unisexual, as in most mosses. -Homosporous plants include liverworts, mosses, hornworts, Lycopodium, most of Pterophyta, and horsetails. Contrast the gametophytes of bryophytes and seed plants.
Why do ferns live in damp environments?
Most ferns are confined to wet areas because of the naked sperm produced during their gametophyte life-cycle. Ferns are classified as Pteridophytes, generally imperfectly adapted to totally dry land areas, unlike the more advanced Angiospermophyta, also called flowering plants, which are more widespread.
Why do Mosses only live in wet places?
Mosses can only survive in the water as it is lacking a vascular system, unlike other plants. So mosses can’t transport water and mineral to its various parts instead they rely on osmosis to allow a cell to cell transport, so being in damp areas would be beneficial for them.
Why did Fern die?
Fern killed it, ridding himself of its influence once and for all. However, with no Grass Demon to control him, Fern began to deteriorate, as he can have no body without the Grass Demon. After waking up, the Gum War was called off but GOLB descended, thrusting everyone into a new battle.
