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.
Embryo, between the 3rd and 8th week. Fetus, after the 8th week
In short, an embryo undergoes both cellular division and cellular differentiation to become a fetus. This is achieved by the genetic program present in the cell(s) which controls both mentioned processes. It is the stage of developing mammal.After 9th week of fertilisation,the embryo can be called foetus.
Once the zygote becomes an embryo it starts developing all of its organs, nervous system etc. then after 8 weeks of development everything is there so it becomes a fetus, and the fetus just grows bigger.
The radicle (embryonic root) is the part of the embryo which emerges first.- HAO - :))
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.
Infant.Zygote, Embryo, Foetus.
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.
zygote embryo foetus 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.
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.
The answer to your question is a zygote. From there, it develops to an embryo and a foetus. Happy science!!!
