Answers (1)
The differences between zygote and foetus are listed below-
Zygote-
The zygote formed after the fertilisation of the male sperm and female ovum.
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.
Foetus-
A foetus is the embryo stage in which all the body parts can be identified.
