Vedclass · Answer

(C) Statement $I$ is correct: In approximately $40\%$ of angiosperms, the generative cell divides mitotically to form two male gametes before the pollen grains are shed, resulting in a $3$-celled stage. In the remaining $60\%$ of species, pollen grains are shed at the $2$-celled stage.Statement $II$ is incorrect: The inner wall of the pollen grain is called the intine. It is a thin and continuous layer made up of cellulose and pectin. It is not discontinuous; rather, the exine (outer layer) is discontinuous at the germ pores.
