Question
Given below are two statements One is labelled as Assertion A and the other is labelled as Reason R.Assertion (A): The first multicellular gametophyte in the life cycle of moss is protonema stage Reason (R): Protonema is the creepy, filamentous stage formed from germination of spore .
Solution
Assertion (A): False. The protonema stage is not a multicellular gametophyte. It is a stage in the life cycle of mosses, but it is not the first multicellular gametophyte. The first multicellular gametophyte in the life cycle of moss is the leafy shoots that grow from the protonema.
Reason (R): True. The protonema is a creeping, filamentous stage that is formed from the germination of a spore. It is the first stage in the life cycle of mosses.
So, while the Reason (R) is correct, the Assertion (A) is incorrect. The protonema stage is not a multicellular gametophyte, but it does lead to the development of the first multicellular gametophyte in the life cycle of mosses.
