Answer 2

Starting with a fertilized egg(zygote), a series of five cell divisions would produce an embryo with 32 cells arranged in the layers.

Explanation -

EMBRYOGENESIS -

• 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.
• The process of cell division is termed cleavage that forms blastula from the zygote.
• Blastocyte is then implanted that forms trophoblast in which cells are arranged in two layers as inner and outer cell mass.
• The early embryo is formed by gastrulation of the three germinal layers that contain 32 cells.
• The early embryo further forms the complete embryo and develops into a fetus.
