botany pictorial feature of plant kingdom classification of bryophytes types of bryophytes bryophyta

  1. The sporophyte is dependent on gametophyte for support, shelter and nutrition

  2. The sporophyte is haploid

  3. The gametophyte is diploid

  4. The gametophyte is dependent on sporophyte for support, shelte and nutrition

Show answer
Correct Option: A
Explanation:

Bryophytes are gametophyte dominant, meaning that the more prominent, longer-lived plant is the haploid gametophyte. The diploid sporophytes appear only occasionally and remain attached to and nutritionally dependent on the gametophyte.

So, the correct answer is A. (The sporophyte is dependent on gametophyte for support,shelter and nutrition)
