When pollen grains are shed,they are in a two-celled stage and double fertilization cannot occur.

Vedclass · Answer

(A) Statement $A$ is incorrect because double fertilization is a characteristic feature of angiosperms,which occurs after the pollen grain reaches the stigma and forms a pollen tube. The shedding of pollen in a two-celled stage (vegetative and generative cell) does not prevent double fertilization; rather,the generative cell divides into two male gametes during the growth of the pollen tube. Statement $B$ is correct as the vegetative cell is larger and has abundant food reserves. Statement $C$ is correct as pollen viability varies from minutes to months depending on the species. Statement $D$ is correct as the intine is the inner wall of the pollen grain composed of cellulose and pectin.
