Answer 2

Required Answer:

☑Sexual reproduction takes place in human beings.Male reproductive organs(testes) produce sperm (male gametes) while the female reproductive organ(ovaries) produce ova (female gametes).

☑The sperms are ejected inside female bodies where they fuse with ovum and forms zygote (called internal fertilization).

☑The zygote begins to develop into an embryo that attaches to the uterus wall of a female.

☑The embryo further multiplies into many cells and develops further into a stage where all the hands and legs of the baby can be seen as foetus and later, a baby is born.
