Answers (1)
The correct option is Option 1) Both A and R are correct, and R is the correct explanation of A.
Assertion A states that the first stage of the gametophyte in the life cycle of a moss is the protonema stage. This is correct. In mosses, the gametophyte generation begins with the development of a filamentous structure called a protonema. The protonema is the first stage in the life cycle and is formed from the germination of moss spores.
Reason R provides the correct explanation for Assertion A. It states that the protonema develops directly from spores produced in the capsule. This is also correct. The spores of mosses are produced within the capsule, which is part of the sporophyte generation. When the spores are released and land in a suitable environment, they germinate and give rise to the protonema.
Therefore, both Assertion A and Reason R are correct, and Reason R provides the correct explanation for Assertion A.
