MCQ
Male gametophyte in angiosperms produces
- Asingle sperm and two vegetative cells
- Bthree sperms
- ✓two sperms and a vegetative cell
- Dsingle sperm and a vegetative cell.
✓
Answer
Correct option: C.
two sperms and a vegetative cell
c
(c) : The protoplast of the male gametophyte divides mitotically to produce two unequal cells — a small generative cell and a large vegetative cell. The generative cell divides later into two nonmotile male gametes (or sperms). Thus, the male gametophyte in angiosperms produces two sperms and a vegetative cell. The vegetative cell, later on, grows to produce pollen tube.
