Answer:
The correct answer is option (2) Vegetative cell.
Explanation:
Mature pollen grain is the male gametophyte of angiosperms that consists of two cells, namely the generative cell and the tube cell. The generative cell divides to form two sperm cells, while the tube cell elongates to form the pollen tube that delivers the sperm cells to the female gametophyte for fertilization.
The vegetative cell is present in the immature pollen grain and is responsible for the growth and development of the pollen tube. However, the vegetative cell degenerates during the maturation of the pollen grain, and hence it is absent in the mature pollen grain.
Therefore, the correct option is (2) Vegetative cell, which is absent in the mature pollen grain of angiosperms.
The correct answer is option (2) Vegetative cell.
