7 months it is a fetus
at 2 and a half months its not an embryo anymore its already implated intself into the uterine lining and becomes a fetus. but the fetus is about and inch and a half long by then i would say.
An embryo typically develops into a fetus around 8 weeks after fertilization. At this point, the major organs have begun to form and the fetus starts to resemble a human.
After two weeks the embryo becomes a fetus and after nine months the fetus becomes a child and after seventy years the child becomes a corpse.
An embryo typically takes about 8 weeks to develop into a fetus. This period marks the end of the embryonic stage and the beginning of the fetal stage in human development.
An embryo can last for about 5-7 days after fertilization before it implants into the uterus. After implantation, the embryo continues to develop into a fetus throughout pregnancy.
If it's a human embryo, about nine months. If you're a mouse embryo, about twenty days. Gestation time in mammals varies species to species, but it's generally safe to say the bigger the animal, the longer the gestation.
At 34 weeks, the fetus is roughly 18inches (45cm) from top to toe
You've got it confused I'm afraid - the embryo forms FROM the egg. It doesn't move anywhere. If you're talking about a bird or reptile egg, the shell forms around the embryo and yolk sac during its passage through the mother's body.
9 months to term.
An embryo is considered to have transformed into a fetus at around 8 weeks of gestation following conception. This marks the point where key organs have formed and the basic body structure is in place. At this stage, the developing organism is referred to as a fetus.
A human fetus can open it's eyes at 26-27 weeks.
A zygote is called a fetus at the end of the eighth week after fertilization, when all major organ systems are in place. At this stage, the developing organism is less than 1 inch long and is starting to resemble a human being in shape.
