Double fertilization in plant
WebThe endosperm is a tissue produced inside the seeds of most of the flowering plants following double fertilization.It is triploid (meaning three chromosome sets per nucleus) in most species, which may be auxin-driven. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein.This can make endosperm … WebApr 9, 2024 · This is called a double fertilization. After fertilization, the zygote divides to form two cells: the upper cell, or terminal cell, and the lower, or basal, cell. The division of the basal cell gives rise to the suspensor, which eventually makes connection with the maternal tissue. The suspensor provides a route for nutrition to be transported ...
