Expert Answer
Gametes are haploid reproductive cells that unite during sexual reproduction to form a new cell called a zygote. In humans, male gametes are sperms and female gametes are ova (eggs).
Zygote is a diploid cell resulting from the fusion of two haploid gametes.
Embryo is an animal organism in the early stages of growth and differentiation. In humans, embryo is an unborn human baby, esp. in the first eight weeks from conception, after implantation but before all the organs are developed.
