During cell division in a zygote, one cell divides and forms a heart cell and another cell divides and forms a brain cell. which of the following best describes the process that is taking place a. zygotation b. meiosis c. mitosisd. fertilization e. none of the above

e,

Explanation:

The process is called Embryonic  differentiation. It is the process where  cells of embryo  undergo division to diverse  specialised structures of  tissues and organs during  Embryogeneis (development  of embryo).The differentiated cells are pluoripotent embryonic stem cell.

 The differentiation is important because   different   cell types of specific functions are in the  embryo. In order to  assume their specific  functions for embryo developments and identity, they must be differentiated 'that is  developed and assigned to  perform specific roles.

It is preceded by fertilisation and Cleavage; influenced by the  internal  factors of cells,as well as,  extracellular factors  of the cell medium.
