An embryo forms first during pregnancy, after fertilization of the egg by sperm. It develops into a fetus around the end of the eighth week of pregnancy.
Embryo, between the 3rd and 8th week. Fetus, after the 8th week
Well, embryo is the developing stage of a zygote(fertilised egg) when it repeatedly divides itself into a ball of cells to form the different tissues and then the organs of the baby. The stage when the hands, legs , and different body parts of the baby can be identified is termed as the foetus. So, in accordance with your question the stage of the foetus is more developed. However the foetus is not the fully developed stage. The foetus once completely developed , the baby is born.
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.
The first step of embryo screening is typically to obtain a sample of cells from the developing embryo. This can be done through techniques such as biopsy or removing a few cells from the embryo for genetic analysis.
The first organ to form in an embryo is the heart. It starts to develop early in gestation and is essential for pumping blood and circulating nutrients throughout the body as the embryo grows.
An unborn baby that is less than 8 weeks old, is an embryo, after this it is classified as a foetus.
A Foetus is formed by the growth and development of an embryo.
Foetus. You call it as an embryo in first 8 weeks.
The embryo will develop into a foetus in the womb.

Babies don't become embryos, it's the other way around. A fertilised egg becomes a zygote, a zygote becomes an embryo, an embryo becomes a foetus, a foetus becomes a baby.
A baby-to-be is an unborn child, a child which has not yet been born - an embryo or foetus.
The heartbeat starts when it's a embryo and at week 5-6.
A Foetus is formed by the growth and development of an embryo. A Foetus is an unborn baby in the uterus in the later stages of development (after 8 weeks till birth). A Foetus is also multicellular. The body features of developing baby can be identified.
The answer to your question is a zygote. From there, it develops to an embryo and a foetus. Happy science!!!
No, a reptile has the ability to lay eggs. Mammals give birth to their young after a period of time, as the egg develops inside them, to first become an embryo, and then a foetus.
it has a large food store so the egg can develope into a foetus
