Answer 1

❤ hOlA mAtE ❤

Embryonic development also embryogenesis is the process by which the embryo forms and develops . In mammals , the term refers chiefly to early stages of prenatal development , whereas the terms fetus and fetal development describe later stages .

Embryonic development starts with the fertilization of the egg cell ( ovum ) by a sperm cell , ( spermatozoon ) . Once fertilized , the ovum is referred to as a zygote , a single diploid cell . The zygote undergoes mitotic divisions with no significant growth ( a process known as cleavage ) and cellular differentiation , leading to development of a multicellular embryo .
