Vedclass · Answer

(A) The correct answer is $A$. In a mature pollen grain,there are two cells: the vegetative cell and the generative cell. The generative cell later divides to form two male gametes. Therefore,stating that it contains a 'male gamete' instead of a 'generative cell' is incorrect. Option $B$ is correct as pollen grains are generally spherical measuring $25-50 \ \mu m$. Option $C$ is correct as the exine layer has germ pores where sporopollenin is absent. Option $D$ is correct as the exine is composed of the highly resistant organic material,sporopollenin.
