Summary Introduction
To determine: The definition of the terms cleavage and blastula.
Introduction: The embryos of different organisms look similar as they follow the similar mechanism of fertilization followed by zygotic and embryonic cleavage. However, during the course of embryonic development, the cells undergo modification that helps them to distinguish from other organisms.
