Vedclass · Answer

(D) The correct answer is $D$. $1$. The exine of pollen grains is composed of sporopollenin,which is one of the most resistant organic materials known. $2$. Pollen grains of many species,such as Parthenium (carrot grass),cause severe allergies and bronchial afflictions in some people. $3$. Pollen grains can be stored for years in liquid nitrogen (at $-196^{\circ}C$) and used in crop breeding programs. $4$. The tapetum is the innermost layer of the microsporangium wall that provides nourishment to the developing pollen grains. It does not help in the dehiscence of the anther; rather,the endothecium layer is responsible for the dehiscence of the anther.
