Vedclass · Answer

(B) The outer layer of the pollen grain is known as the exine $(A)$. It is composed of a highly resistant organic material called sporopollenin $(B)$. This layer is discontinuous and is absent at specific regions known as germ pores $(C)$,which allow for the emergence of the pollen tube during germination. Therefore,the correct sequence is $A$-exine,$B$-sporopollenin,$C$-germ pore.

The outer layer of a pollen grain is called $A$. This is made up of $B$. This layer is absent at the $C$. Fill in the blanks $A, B$,and $C$.
