Explanation / Answer

1. The answer to this question is the option a - mosses. They appeared first in land plant evolution.

2. The answer to this question is the option b - dependent on the gametophyte generation. In bryophytes, the sporophyte is dependent on the gametophyte for nutrition. Hence gametophyte is dominant in bryophytes.

3. The answer to this question is the option d- all of the above. They use all pigments

4. The answer to this question is option b - there are two phases, a sporophyte, and a gametophyte

5. The answer to this question is option b - is common to all land plants

6. The answer to this question is option d - all of the above.

7. The answer to this question is option d - asexual reproduction. Gemma develops into a new plant by a process called fragmentation. At first, they detach from the plant tissue and then develops into a new individual.

8. The answer to this question is option a - all of the above

9. The answer to this question is option b - is the product of spore germination of moss.

10. The answer to this question is option a - branch

11. The answer to this question is option d - all of the above

12. The answer to this question is the option a - xylem and phloem

13. The answer to this question is option a - Psilotum lacks roots

14. The answer to this question is option d - gametophyte

15. The answer to this question is option a - a plant that grows on another plant

16. The answer to this question is option d - are so called because most produce strobili

17. The answer to this question is option d - all of the above

18. The answer to this question is option d - Horsetails are "not" the members of the subphylum Sphenophyta. They are the members of the "phylum" Sphenophyta.

19. The answer to this question is option d - all of the above

20. The answer to this question is option a - produced by mitosis within the sporangium.
