Question

Arrange the following events of the life cycle of Bryophytes in the correct sequence:

I) Formation of Spores, II) Gametes Formation, III) Formation of Gametophyte, IV) Fertilisation, V) Embryo Formation

• A. III, IV, V, II, I
• B. V, I, II, III, IV
• C. I, III, IV, V, II
• D. III, II, IV, V, I

Answer 1

The correct option is D

III, II, IV, V, I

The correct option is D.

Explanation of correct option:

1. Gametophytes are produced by Bryophytes.
2. Gametophytes are haploid.
3. Antheridium(male organ) produces antherozoids.
4. Archegonium (female organ) produces eggs.
5. Gametes fertilize and form a diploid zygote.
6. Zygote develops into a multicellular sporophyte/ embryo.
7. Some cells of the sporophyte undergo meiosis to produce haploid spores.
8. Spores germinate to produce gametophytes, and the cycle continues.

Final answer:

The correct sequence of steps in the life cycle of Bryophytes is the Formation of Gametophyte, Gametes Formation, Fertilization, Embryo Formation, and Formation of Spores.
