Summary Introduction

Concept Introduction: Cleavage is a process of repeated mitotic divisions where the enormous amount of cytoplasm is distributed to form several small cells. Cleavage is a part of development.

Explanation

At the end of cleavage the blastula is formed. The blastula has a covering called as blastoderm and the cavity inside called as blastocoel. The blastula is made of cells called as blastomeres. The size of the blastula varies from species to species.
