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
- AA is not correct but R is correct
- 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.
