Vedclass · Answer

(B) In plants,the sporophyte generation is diploid $(2n)$ and the gametophyte generation is haploid $(n)$.$(a)$ Pollen grains (gametophyte) are inside the anther (sporophyte). This represents two generations.$(b)$ Germinated pollen grain is a single generation (gametophyte).$(c)$ Seed (new sporophyte) is inside the fruit (parent sporophyte). This represents two generations.$(d)$ Embryo sac (gametophyte) is inside the ovule (sporophyte). This represents two generations.Therefore,$(a), (c),$ and $(d)$ consist of two generations,one within the other.

$(a)$ Sporopollenin	$(1)$ Spindle-shaped nucleus
$(b)$ Cellulose,Pectin	$(2)$ Exine
$(c)$ Vegetative cell	$(3)$ Intine
$(d)$ Generative cell	$(4)$ Irregularly shaped nucleus
