Q1 / 200 · NEET 2023 (All India) · Botany

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). 

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:

  • A
    A is not correct but R is correct
  • Correct answer
    B
    Both A and R are correct and R is the correct explanation of A
  • C
    Both A and R are correct and R is NOT the correct explanation of A
  • D
    A is correct but R is not correct

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.

Hence, the correct answer is option: 'B'.
