Chapter 50.1, Problem 2SB

Summary Introduction

To review:

The primary cell layers of embryo and the process responsible for producing them.

Introduction:

The development of organism starts with the fusion of male and female gametes, to form zygote. Once the zygote is formed, it is cleaved into smaller cells called blastomeres. These blastomeres initially form a ball of cells and later this ball hollows out to form blastula in which the cells surround a fluid filled space. These cells of blastula then rearrange themselves to form three layers of cells, which later form specialized tissues or organs.
