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 $(A)$
2 Both (A) and (R) are true but (R) is not the correct explanation of (A).
3 (A) is true but (R) is false
4 (A) is false but (R) is true
Explanation:
The life cycle of Funaria has two distinct individuals. One of these is haploid, independent, leafy moss plants, the other is diploid. There is alternation of haploid gametophytic and diploid sporophytic phases, one becoming parent to the other.

Funaria's male gametes are
1 Poly flagellate
2 Mono flagellate
3 Biflagellate
4 Tetra flagellate
Explanation:
Funaria male gametes are biflagellate in which androcyte mother cells are formed from division and redivision of the primary and androgonial cell. Each androcyte mother cell divides to form two androcytes. - The Androcytes transform into biflagellate antherozoids or sperms.

Which of the following is known as bog moss?
1 Polytrichum
2 Funaria
3 Sphagnum
4 Porella
Explanation:
Bog moss is an aquatic moss also known as peat moss or cotton moss. Sphagnum is known as the bog moss, it is a living moss found in wet and boggy areas. It can store water as both living and dead plants hold large quantities of water inside their cells. It also regulates moisture and air around the plant roots for making suitable conditions of root growth and development.

Calyptra develops from
1 venter wall of archegonium
2 outgrowth of gametophyte
3 neck wall of archegonium
4 paraphysis of the archegonial branch
Explanation:
Exp. A Calyptra develops from venter wall of archegonium. Calyptra is a covering that develops from the venter wall of archegonium in bryophytes and pteridophytes. Where this is an enlarged archegonia center that protects the capsule which in turns contains the embryonic sporophytes. It acts as a transpiration shield around the immature capsule and provides protection to the young capsule.
