Given below are two statements: One labelled as Assertion A and the other 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 most appropriate answer from options given below:
- A
Both A and R are correct and R is the correct explanation of A
- B
Both A and R are correct but R is NOT the correct explanation of A
- C
A is correct but R is not correct
- D
A is not correct but R is correct
The dominant phase in a moss life cycle is the gametophyte, which begins with the protonema. The protonema arises directly by germination of the haploid spores released from the capsule of the sporophyte. Hence both statements are correct and R provides the mechanism behind A.
