Assertion (A) : The first stage of gametophyte in the life cycle of moss is protonema stage.
Reason (R): Protonema develops directly from spores produced in capsule.
In the light of the above statements, choose the correct answer from the options given below:
Options

- BBoth A and R are correct and R is the correct explanation of A
- CBoth A and R are correct and R is NOT the correct explanation of A
- DA is correct but R is not correct
Correct answer
B. Both A and R are correct and R is the correct explanation of A
Step-by-step solution
The predominant stage of the life cycle of a moss is the gametophyte which consists of two stages. The first stage is the protonema stage, which develops directly from a spore. Capsule of the sporophyte contains spore which gives rise to protonema. Thus, reason correctly explains the assertion.
