Detailed explanation-1: -There will be 32 cells after a zygote goes through 5 mitotic cell divisions.
Detailed explanation-2: -For the first 12 hours after conception, the fertilized egg remains a single cell. After 30 hours or so, it divides from one cell into two. Some 15 hours later, the two cells divide to become four. And at the end of 3 days, the fertilized egg cell has become a berry-like structure made up of 16 cells.
Detailed explanation-3: -Starting with a fertilized egg(zygote), a series of five cell divisions would produce an embryo with 32 cells arranged in the layers. The process of formation of an embryo from a zygote by the divisions of cells. It involves the formation of a multi-cellular complex organism from a unicellular zygotic cell.
Detailed explanation-4: -(e) At about 14 days after fertilisation, following implantation, the early embryo consists of about 2000 cells.
Detailed explanation-5: -The fertilized egg (zygote) divides repeatedly as it moves down the fallopian tube to the uterus. First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst.
