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 the options given below
1 A is not correct but $\mathrm{R}$ is correct.
2 Both $\mathrm{A}$ and $\mathrm{R}$ are correct and $\mathrm{R}$ is the correct explanation of $\mathrm{A}$.
3 Both $\mathrm{A}$ and $\mathrm{R}$ are correct but R is NOT the correct explanation of $\mathrm{A}$.
4 A is correct but R is not correct.
Explanation:
The plant body of mosses is very simple. It has a small branched stem with spirally arranged simple leaves, multicellular hairy out growths, called rhizoids. - Protonema is a stage that is creepy, green, branching and frequently filamentous. - Protonema is a haploid autonomous, gametophytic stage when a moss, first grow from the spore. It grow as a protonema which develop into leafy gametophyte.

Statement (S) : All bryophytes are homosporous Reason (R) : In bryophytes, gametophytic and sporophytic bodies are conspicuously different and the life cycle is called haplo-diplontic. Which of the following is true?
1 Both (S) and (R) are true and (R) is the correct explanation of (S)
2 Both (S) and (R) true, but (R) is not the correct explanation of $(\mathrm{S})$
3 (S) is true, but (R) is false
4 (S) is false, but (R) is true
Explanation:
All broyphytes are homosporous because the antheridium and the archegonia are present on the same plants. Bryophytes exhibit haplo-diplontic life cycle as the gametophytic phase is prominant $(60 \%)$ in their life cycle. - The sporophytes is diploid, dependent on the gametohyte for nutrition and produces spores by mitosis.

Assertion (A) : The life cycle in Funaria is called diplohaplontic. Reason (R) : In Funaria, there is alternation of haploid gametophytic and diploid sporophytic phases, one becoming parent to the other. The correct answer is
1 Both (A) and (R) are true and (R) is the correct explanation of $(\mathrm{A})$
2 Both (A) and (R) are true and (R) is not the correct explanation of $(\mathrm{A})$
3 (A) is true, but (R) is false
4 (A) is false, but (R) is true.
Explanation:
In the life cycle of Funaria there occurs two distinct individuals. One of these is haploid independent leafy moss plant. The other is diploid leafless sporogonium. It is partially dependent on the leafy gametophyte for its nutrition. Life cycle of Funaria diplohaplontic.
