Formation of endosperm before fertilization

Vedclass · Answer

(D) Conifers belong to the group $Gymnosperms$,while grasses belong to the group $Angiosperms$.In $Gymnosperms$,the endosperm is formed before fertilization as a result of the development of the female gametophyte (haploid tissue).In $Angiosperms$ (like grasses),the endosperm is formed after fertilization through the process of double fertilization (specifically,triple fusion involving the fusion of one male gamete with two polar nuclei to form a triploid primary endosperm nucleus).Therefore,the formation of endosperm before fertilization is a characteristic feature that distinguishes $Gymnosperms$ (conifers) from $Angiosperms$ (grasses).
