Answer: 1. Tapetum helps in the dehiscence of anther

The tapetum nourishes the developing pollen grains; it does not help in anther dehiscence (that is done by the endothecium and stomium). So option 1 is not true.

Exine is made of sporopollenin, pollen causes allergies in many people, and pollen stored in liquid nitrogen (-196 C) is used in crop breeding. These are true.
