Where does fertilization take place in the moss life cycle?

In the moss life cycle, fertilization takes place in the archegonium of the gametophyte. Mosses have diploid and haploid generations. Gametophytes, spores, sperm, and eggs are all haploid.

What conditions must exist for the sperm to reach the egg in moss?

Bryophytes also need a moist environment to reproduce. Their flagellated sperm must swim through water to reach the egg. So mosses and liverworts are restricted to moist habitats.

Why do mosses need water for fertilization?

Bryophytes though grow on soil but need water for sexual reproduction. The sperms of bryophytes are flagellated and eggs are non-motile. ... So, in order to accomplish fertilization sperm must be provided with water. So that sperm can whip its flagella in water and swim to egg to fertilize it.

How does moss reproduce?

Mosses reproduce by branching and fragmentation, by regeneration from tiny pieces of leaves or stems, and by the production of spores. The spore, under favourable conditions, germinates and grows into a branching green thread (protonema).

What occurs in the life cycle of a moss?

A moss is a member of the plant phylum Bryophyta. ... The life cycle of a moss, like all plants, is characterized by an alternation of generations. A diploid generation, called the sporophyte, follows a haploid generation, called the gametophyte, which is in turn followed by the next sporophyte generation.

What do the moss life cycle and the fern life cycle have in common?

Both mosses and ferns have gametophyte and sporophyte stages in their life cycle.

What occurs in the life cycle of a moss but not in the life cycle of a gymnosperm?

In moss, sperm and egg cells are produced after haploid spores are separated from the sporophyte plant- occurs in the life cycle of a moss but not in the life cycle of a gymnosperm.

What feature of the moss life cycle differs from the life cycle of other land plants?

All bryophytes have a dominant gametophyte stage in their life cycle. During this stage, the plant is haploid and the sex organs that produce the gametes are developed. Bryophytes are unique compared to many other plant species in that they remain in this stage for long periods.

Which is needed by moss to reproduce?

Mosses reproduce by spores, which are analogous to the flowering plant's seed; however, moss spores are single celled and more primitive than the seed. Spores are housed in the brown capsule that sits on the seta. ... Pieces of the moss body can break off, move by wind or water, and start a new plant if moisture permits.

Why do moss and ferns need water to reproduce?

To reproduce sexually, mosses and ferns produce sperm and eggs. The motile sperm must be able to swim through water to reach and fertilize the eggs, which is why most mosses and ferns live in damp habitats. Even in the absence of rainfall, moisture-laden fog or morning dew produce enough water to accomplish this task.

Why do mosses and ferns need water directly for reproduction?

Ferns have both roots and vascular tissue and therefore, can grow larger than moss species, but like the mosses, ferns require water for reproduction. The sperm cells have flagella and must swim through a water film to fertilize the egg.

Why do mosses need moist environment?

Mosses are found in moist areas because they are non-vascular plants and must absorb their water.

How does Moss protonema reproduce?

From spores to new plants

If a spore falls onto suitable, moist conditions it germinates into a 'protonema'. This is a thin, filament like, branching plant. From this threadlike plant grow 'buds' and these buds are what become the new male and female plants. And the cycle of sexual reproduction is completed.

Which statement best describes fertilization in the moss life cycle?

Which statement best describes fertilization in the moss life cycle? Flagellated sperm swim in a film of water on the surface of the plant to reach an egg. The slender, rootlike structures found in nonvascular plants are called ____.

What is unusual about the reproductive cycle of a moss?

The mosses (and all bryophytes) have an alternation of generations life cycle that is unusual for two reasons: The haploid form is the dominant generation (larger, long-lived, and photosynthetic) The diploid form is the lesser generation (smaller, short lived and nutritionally dependent on the haploid form).
