What is ebryo?

Answer 1

is a multicellular diploid eukaryote in its earliest stage of development, from the time of first cell division until birth, hatching, or germination. In humans, it is called an embryo until about eight weeks after fertilization (i.e. ten weeks LMP), and from then it is instead called a fetus.

Answer 2

An embryo is the early developmental stage of an organism after fertilization, typically characterized by the formation of basic organ structures but not yet fully developed. In humans, the embryo stage lasts from fertilization up until about the eighth week of pregnancy. During this time, the embryo undergoes rapid cell division and differentiation.
