Textbook Problem

From a developmental standpoint, a seed is best described as a(an):

a. epicotyl.

b. endosperm.

c. ovary.

d. mature spore.

e. mature ovule.

Summary Introduction

Introduction:

In flowering plants, the process of fertilization of egg cells by sperm cell results in the formation of an embryo called seed. This seed is present within the flower. It is observed that this seed absorbs nutrition from endosperm cells that are formed during double fertilization.

Explanation

Justification/ Explanation for the correct answer:

Option (e) is given as mature ovule. A seed develops when the egg fertilizes with the ovule. From a developmental standpoint, the seed comprises two regions within the seed coat which are formed by the ripened ovule. These regions include smaller lower embryo region and larger upper region with cotyledons and endosperm. This set lies within the mature or ripened ovule (seed coat), so the seed is described as mature ovule from a developmental standpoint. Hence, option (b) is correct.

Explanation for the incorrect answers:

Option (a) is given as epicotyl. This is the part of the seedling stem that lies above the cotyledons. This region is important because the shoot apex and leaf primordial extend from this region’s tip. It is a part of the mature seed. So, it is incorrect.

Option (b) is given as endosperm...
