Vedclass · Answer

(B) The pollen grain wall consists of two layers: the outer exine and the inner intine.The exine is made of sporopollenin,which is one of the most resistant organic materials known.However,the exine is absent at certain places,and these apertures are known as germ pores.During the process of fertilization,the pollen tube emerges from the pollen grain through one of these germ pores,which is essential for pollen germination and the delivery of male gametes to the ovule.

Choose the correct option with respect to germ pore.
