(a)

Summary Introduction

To determine:

The diploid number of chromosomes in the given plant.

Introduction:

Meiosis is also referred as reduction division. It is a type of cell division, in which the chromosome number gets reduced to half. Meiosis completes in two stages; meiosis I and meiosis II. Both contain four phases; prophase, metaphase, anaphase, and telophase. Meiosis occurs only in the reproductive cells or sex cells of the body.

Mitosis is a type of cell division, which results in the formation of two identical daughter cells. It only occurs in vegetative cells and the ploidy of the cells remains the same. So, it is also called equational division. The whole process of mitosis completes in four phases, namely, prophase (I phase), metaphase (II phase), anaphase (III phase), and telophase (IV phase).
