Vedclass · Answer

(A) In angiosperms,double fertilization occurs. $1$. The primary endosperm nucleus $(PEN)$,which is formed by the fusion of two polar nuclei and one male gamete,develops into the primary endosperm cell $(PEC)$. This cell further divides to form the endosperm,which provides nutrition to the developing embryo. Thus,statement $A$ is correct. $2$. The zygote is formed by the fusion of the egg cell and a male gamete. The zygote undergoes mitotic divisions to develop into an embryo. Thus,statement $R$ is correct. Therefore,both $A$ and $R$ are correct.

List-$I$	List-$II$
$(a)$ Stamen	$(i)$ Microsporangium
$(b)$ Pistil	$(ii)$ Microsporophyll
$(c)$ Anther	$(iii)$ Megasporangium
$(d)$ Ovule	$(iv)$ Megasporophyll

$A$ - Endosperm is formed by the primary endosperm cell.
$R$ - Embryo is formed from the zygote.
