5. Give two differences between a zygote and a foetus.
Answers (1)
Zygote-
The zygote formed after the fertilisation of 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-
The stage of the embryo in which all the body parts can be identified is called a foetus.
