What does each structure does during the germinal stage according to the brief below
The germinal stage
Each of us begins our life as a zygote, a single cell not much larger than
the full stop at the end of this sentence. This is when conception has
occurred, when the male’s sperm cell has fertilized the female’s ovum
(egg). During this stage, the zygote divides into a number of identical cells by means of a process called mitosis. About
four days after conception, the cell mass, now comprising some 100 cells,
emerges from the fallopian tube and moves into the uterus. It is at
conception that our genetic heritage is determined, as the genes from the
sperm and those from the ovum merge to form a new and unique person.
1. Zygote: The zygote is the single cell formed after conception. It divides into a number of identical cells through mitosis.
2. Cell mass: The cell mass, comprising about 100 cells, moves into the uterus from the fallopian tube about four days after conception.
3. Genetic heritage: At conception, the genetic heritage of the individual is determined as the genes from the sperm and ovum merge to form a new and unique person.
