Q. Which one of the following statements is wrong ?
A) When pollen is shed at two-celled stage, double fertilization does not take place
B) Vegetative cell is larger than generative cell
C) Pollen grains in some plants remain viable for months
D) Intine is made up of cellulose and pectin
Explanation
[Solution from source] Pollen shed at the two-celled stage still achieves double fertilisation, because the generative cell divides into two male gametes inside the pollen tube. The other statements are true: the vegetative cell is larger, some pollen (e.g. of Solanaceae) stays viable for months, and the intine is cellulose and pectin. Answer (1).
