Beginning with the germination of a moss spore, what is the sequence of structures that develop after germination?
i. | embryo |
ii. | gametes |
iii. | sporophyte |
iv. | protonema |
v. | gametophore |
1. | iv →i → iii → v → ii |
2. | iv → iii → v → ii → i |
3. | iv → v → ii → i → iii |
4. | iii → iv → v → ii → i |
Assertion(A): | Mosses are evolved from algae. |
Reason(R): | Protonema of mosses is similar to some green algae. |
1. | Both (A) & (R) are true and (R) is the correct explanation of (A) |
2. | Both (A) & (R) are true but (R) is not the correct explanation of (A) |
3. | (A) is true statement but (R) is false |
4. | Both (A) and (R) are false statements |
1. | The haploid generation grows on the sporophyte generation |
2. | Spores are primarily distributed by water currents |
3. | Antheridia and archegonia are produced by gametophytes |
4. | The sporophyte generation is dominant |
