Question

In the moss life cycle, the gametophyte
A. Consists of leafy green shoots
B. Is the heart-shaped prothallus
C. Consists of a foot, a stalk, and a capsule
D. Is the dependent generation

Answer 1

Hint: Mosses are bryophytes which are known as amphibians of the plant kingdom as they live both on land and water and the gametophyte is the main plant body of them.

Complete answer: First of all you should know what moss life cycle is. Moss life cycle means the life cycle of bryophytes and bryophytes live on both land and they require water for their reproduction and therefore they are known as amphibians of the plant kingdom. Mosses are thallus like as they do not have two root stems or body and the gametophyte is the main plant body of them which has a leaf-like structure. Their parts look like stem-like and leaf-like structure but not actual parts. Let's look at options now-
>Option A is Consists of leafy green shoots. This option is the correct option as in the moss life cycle, the gametophyte is the main plant body and it consists of leafy green shoots as their parts look stem-like and leaf-like structure. Therefore, this option is the correct one.
>Moving to option B i.e., Is the heart-shaped prothallus. In the moss life cycle, the gametophyte is the main plant body and it is not the heart-shaped prothallus which makes this option incorrect and therefore it gets eliminated.
>Moving to option C i.e., consists of a foot, a stalk, and a capsule. This option is also incorrect as in the moss life cycle, the gametophyte does not consist of a foot, a stalk, and a capsule which makes this option incorrect and thus it gets eliminated.
>Last option D i.e., Is the dependent generation. This is also an incorrect option as in the moss life cycle, gametophyte is not the dependent generation and thus this option is also incorrect and it gets eliminated.
Thus, the correct answer is option A i.e., leafy green shoots.

Note:
Since, the gametophyte in the moss cycle is the main plant body of them which has leaf like structure and also their parts looks like stem and leaf-like structures which makes option A the correct one as option A is that gametophyte consists of a leafy green shoots.
