Chapter 18, Problem 12Q
Summary Introduction

To explain: The reason that cleavage divisions take place without significant increase in the weight of the embryo as a result of short cell cycles that are shorter than those of bacterial fission time.

Introduction: The male and female gametes unite to form the zygote. The zygote then undergoes series of cell divisions called cleavage to develop into a multicellular organism. Cleavage is a process of repeated mitotic divisions where the enormous amount of cytoplasm is distributed to form several small cells. Here, the weight of the embryo does not change.

Summary Introduction

To explain: The phase of the cell cycle that will be reduced during cleavage.

Introduction: The male and female gametes unite to form the zygote. The zygote then undergoes series of cell divisions called cleavage to develop into a multicellular organism.
