EVERYDAY SCIENCE

Detailed explanation-1: -During cleavage the relatively enormous zygote directly subdivides into many smaller cells of conventional size through the process of mitosis (ordinary cell proliferation by division). These smaller cells, called blastomeres, are suitable as early building units for the future organism.

Detailed explanation-2: -Zygotes divide through a process known as mitosis, in which each cell doubles (one cell becomes two, two becomes four, and so on).

Detailed explanation-3: -The zygote divides into two cells by mitosis.

Detailed explanation-4: -The zygote divides meiotically to form haploid spores, which undergo mitosis to form multicellular haploid organisms.

Detailed explanation-5: -For the zygote, the goal is to make more somatic cells. Therefore, it goes through mitosis and gives rise to two daughter cells. This completes the life cycle of the zygote and starts the lifecycle of the new cells. Rounds of the cell cycle continued over and over to form the body you have today.
