Chapter 37.1, Problem 2R

Summary Introduction

To review:

To compare the structure of pollen grain and mature embryo sac and its importance.

Introduction:

The formation of the pollen grain occurs by the division of pollen mother cell. The pollen mother cell further undergoes meiosis to form four haploid microspores. This microspore undergoes microsporogenesis to form mature pollen grain. The megaspore mother cell division leads to the formation of eight-nuclei and seven-celled mature embryo sac.
