Question

Megasporocytes will eventually produce which of the following?

a. pollen grain

b. sporophytes

c. male gametophytes

d. female gametophytes

Short answer

The correct answer is option (D).

Megasporocytes will eventually produce the female gametophyte.

Step-by-step solution

Introduction

A megasporocyte, also known as the megaspore mother cell, is a diploid cell found in the nucellus of a heterosporous plant's ovule.

Reason for Incorrect options

• The male gametophyte is the pollen grain that produces the male gametes.
• The sporophyte is the diploid plant body in a generation that starts with a diploid zygote and ends with haploid spores produced by meiosis.
• The male gametophyte is generated from the microsporangium's microsporocytes in a heterosporous plant body. Pollen grains will form as a result of this.

Reason for Correct Option

Megasporangia are female sporangia found in ferns, gymnosperm cones, and angiosperm blooms. Megasporangia create megasporocytes, which go through meiosis and form megaspores as part of megasporogenesis.

Megagametogenesis is the process by which a megaspore develops into a female gametophyte (embryo sac). The nucleus of a megaspore divides three times during mitosis. One of these eight nuclei will become an egg cell.

Hence, option (d) is the correct answer.
