Question

The correct sequence of events in the life cycle of bryophytes is:
A. Fusion of antherozoid with egg.
B. Attachment of gametophyte to substratum.
C. Reduction division to produce haploid spores.
D. Formation of sporophyte.
E. Release of antherozoids into water.
Choose the correct answer from the options given below.

• A. B, E, A, C, D
• B. B, E, A, D, C
• C. D, E, A, B, C
• D. D, E, A, C, B

Hint:

The bryophyte life cycle involves the alternation of generations: - The gametophyte generation produces gametes, - The sporophyte generation produces spores through reduction division.

Answer 1

The Correct Option is A

The bryophyte life cycle proceeds as follows:
1. B - Gametophyte adheres to the substrate.
2. E - Antherozoids are discharged into water.
3. A - Antherozoid fertilizes the egg.
4. C - Meiosis occurs, yielding haploid spores.
5. D - Sporophyte develops.
The correct sequence is B, E, A, C, D.
