Mosses are ecologically important. I. The last organism to colonize base rocks. II. It decompose rocks making suitable for the growth of higher plant. III. It forms dense mats on soil. IV. It increases the impact of falling rain and soil erosion. Identify the correct answer
1 Only I
2 Only II and III
3 III and IV
4 All of these
Explanation:
Mosses along with lichens are the first organisms to colonise rocks and hence, are of great ecological importance. They decompose rocks making the substrate suitable for the growth of higher plants. Since mosses form dense mats on the soil, they reduce the impact of falling rain and prevent soil erosion.

Mosses possess leaf like, root like and stem like structure. What structure does it represent?
1 Gametophyte
2 Sporophyte
3 Diploid Gametophyte
4 None of these
Explanation:
The plant body of bryophytes may possess root-like, leaf-like or stem-like structures. The main plant body of the bryophyte is haploid. It produces gametes, hence is called a gametophyte.

Mosses along with lichen are of great ecological importance because
1 Help in eclogical succession
2 Prevent soil erosion
3 They colonise barren rocks and decompose rock
4 All of them
Explanation:
Mosses along with lichens are the first organisms to colonise rocks and hence, are of great ecological importance. They decompose rocks making the substrate suitable for the growth of higher plants.

The male gametes of bryophytes are
1 Multiflagellated
2 Biflagellated
3 Non-motile
4 Uniflagellated
Explanation:
The antheridium in Bryophytes produces biflagellate gametes called antherozoids
