An embryo is made up of a single cell.
विकल्प
True
False
उत्तर
This statement is False.
Explanation:
Fertilisation results in the formation of the zygote, which begins to develop into an embryo. The zygote divides repeatedly to give rise to a ball of cells. The cells then begin to form groups that develop into different tissues and organs of the body. This developing structure is termed an embryo. The embryo gets embedded in the wall of the uterus for further development.
