Question

Write about the phases in Bryophyta.

Answer 1

Bryophytes:

1. Bryophytes are non- vascular terrestrial plants.
2. They are known as the amphibians of the plant kingdom as they require water for their propagation.
3. They have two stages in their life cycle i.e sporophyte and gametophyte.

Sporophyte:

1. Sporophyte is a diploid, multicellular plant structure in bryophtes.
2. It develops from the fertilized gamete formed by the gametophytic stage of the plant.
3. It produces spores through asexual, meiotic division.
4. These spores proliferate to become gametophytes.

Gametophyte:

1. Gametophyte is a haploid, multicellular plant structure in bryophytes.
2. It develops from spores formed by the sporophytic body.
3. it produces haploid gametes through mitotic division.
4. These gametes fuse to form a zygote that develops into a sporophyte.
