The answer is Cleavage because Cleavage is the first mitotic divisions of the zygote. There is an increase in the number of cells but a decrease in size of the individual cells.
Within a half hour after fertilization.
The zygote becomes a multicellular organism by means of cell division and differentiation.
about 30-36 hours after fertilization

After 8 successive mitotic divisions of a zygote, there will be 256 cells. Each mitotic division doubles the number of cells, so if the zygote starts with 1 cell, it will be divided into 2, then 4, then 8, and so on, until reaching 256 cells after 8 divisions.
The answer is Cleavage because Cleavage is the first mitotic divisions of the zygote. There is an increase in the number of cells but a decrease in size of the individual cells.

zygote always undergoes mitotic division and all other vegitative cells undergo mitosis meiosis takes place in sex cells

No. The term zygote refers to a much broader period at the earliest stages of an organism's development, from the first fusion of sperm and egg to (form a single celled zygote) through many cell divisions (producing a multi-celled zygote) which matures into a blastocyst. So, zygotes can be one celled, two celled, or many celled.
1.) fertilization of egg by sperm 2.) mitotic cell division of zygote 3.) differentiation of cells into tissues 4.) organ development
As HUMANS, stem cells as they develop into our own specialised cells, as all animals start off as a fertilised egg, and it is our genetics that transform our stem cells into the many different specialised cells we need as humans.
After the zygote forms, its cells divide until they form a hollow ball of cells called a Blastula.
