Embryo consumes the endosperm in plant.
Embryo feed on womb milk in human.
Step-by-step explanation:
In many plant the growing embryo consumes the endosperm before seed maturation; in others, the tissue persists in the seed, providing a reserve for the developing seedling after germination. (In plant).
Aplin says that in the first weeks, womb milk is the embryo's only source of nourishment. This is no accident at the beginning of a pregnancy, the placenta is much larger than the growing embryo, so the pressure of arterial blood would likely dislodge the embryo from the wall of the uterus in human.
