Zygote is the beginning of the formation of baby.
This is the single-celled stage that follows fusion of the haploid egg and sperm.
Stage A
zygote stage, embryonic stage,and fetal stage
embryo
One would think it's embryo but a zygote is not a embryo yet, it is the early stage of what will become a embryo. Zygote is the word used and you can use the word cell since a zygote is the initial cell formed after a sperm and egg have joined. After 1 week it has transformed into a embryo.
Zygote
In order to obtain stem cells, an embryo must be in the blastocyst stage.
CLEAVAGE The cleavage process directly follows the zygote stage. The zygote stage is the earliest developmental stage of an embryo.
zygote stage, embryonic stage,and fetal stage
Zygote
Before the fetal stage is the embryonic stage. The embryo develops into the fetus.
embryo
The amniotic sac forms during the embryonic stage of development, around week 2 after fertilization. It is a protective membrane filled with amniotic fluid that surrounds and cushions the developing embryo/fetus in the uterus.
zygote
The stage of a multicellular organism that develops from a zygote.
It is a stage in the development of an embryo.
Embryo
When the sperm meets the ovum and goes into the zygote .
The stage of a multicellular organism that develops from a zygote.
