Q. Moss plant is a
Solution:
The moss belongs to the Class Bryopsida. The following are the feature of this plant:
1. It has erect gametophyte with multicellular, oblique rhizoids, stem-like erect structure bearing small leafy appendages.
2. The gametophyte possesses distinct antheridia and archaegonia and these organs are multicellular and covered by a sterile jacket.
3. Sperms are biflagellated. They are attracted by the sucrose secretion by the archaegonium after the maturation of egg.
4. The fusion of gametes results in the formation of the diploid zygote. This forms the embryo inside the archaegonia.
5. The embryo grows and forms the sporophyte with the foot, seta, and capsule.
6. The sporophyte is partially dependent on the gametophyte and remain attached by foot. The capsule contains cells with plastids and can perform photosynthesis and thus, provide nutrition to the sporophyte.
