how will you differentiate between a zygote and an embryo?
Answers
an embryo is the previous stage of zugote.
A zygote is a diploid cell resulting from the fusion of two haploid gametes, usually a sperm and egg. A zygote may not develop properly to become an embryo. An embryo is a collection of cells far enough along in its development that it quite possibly may become a fully developed entity. When a zygote divides and become 2 cells, then divides again and becomes 4 cells, some where along this process it becomes an embryo. I think it’s a philosophical question, but clearly is no longer a zygote once it divides.

Zygote vs Embryo
A zygote or a zygocyte is the original cell that comes to creation when a new organism is formed through sexual reproduction. A zygote is formed from the synthesis resulting out of the union of the two distinctive gametes. On the other hand the embryo is the mutlicellular diploid eukaryote in one of the early stages of development. The eukaryote is termed as the embryo, in humans, 8 weeks past the fertilization.
The term ‘zygote’ comes from the root Greek word ‘zygotos’ meaning yoked or ‘to yoke’ or ‘joined’ or to ‘join’. On the other hand, embryo comes from the root Latin word ’embryum’ meaning ‘that which grows’.
Zygote is the first stage in the development process of an organism. It is produced of the process of fertilization occurring amongst the haploid ovum cell from the female and the haploid sperm cell from the male. Both these two cells combine to form the sole diploid cell or the zygote. It is the carrier of the DNA and all the genetic traits derived from the parents. The zygote provides all the genetic information indispensable for the growth of the new organism. On the other hand, embryo refers to that stage in the developing process of the organism which starts from the initiation of the first cell division till the birth (till hatching in amphibians and aves and germination in case of plants). The developing process of the embryo is termed as embryogenesis...............
