Summary Introduction

To explain:

The term “endosperm”.

Introduction:

Double fertilization is a type of fertilization that occurs in angiosperms (flowering plants). In this process, the female gametophyte joins with two male nuclei. Two fertilization take place simultaneously in this process and thus, it is called double fertilization.

Summary Introduction

To determine:

Summary Introduction

To determine:

Whether endosperm is more abundant in mature seed of dicot or of monocot.

Introduction:

A seed is defined as an embryonic plant, which is enclosed within a protective covering (seed coat). New plants germinate from the seeds and thus, seeds are an essential part of the reproductive process of plants.  Plants that produce seeds are called phanerogams. A seed can either be a monocot or a dicot on the basis of the presence of cotyledons.
