Question

What is the primary characteristic of a cell on which first division is made?

Answer 1

Hint: All known species have a cell as their fundamental structural, functional, and biological unit. Because cells are the tiniest units of life, they are sometimes referred to as "building blocks of life." Cells are made up of cytoplasm and a membrane that includes a variety of biomolecules such as proteins and nucleic acids. Cell biology is the study of cells and their functioning.

Complete answer:
In this question we have been asked to point out the primary characteristic of cells on which the most basic classification of cells can be done.
So, the most basic classification of cells is done based on their nature.
On the basis of nature cells can be classified as prokaryotic cells and eukaryotic cells.
1. Prokaryotes are unicellular creatures with no membrane-bound structures, the nucleus being the most notable. Prokaryotic cells are tiny, basic cells that range in size from \[0.1 - 5{\text{ }}\mu m\] in diameter. Examples of prokaryotes include bacteria and archaea which are classified in kingdom Monera in the five kingdom classification scheme.
2. Eukaryotes contain a nucleus and other organelles surrounded by a plasma membrane in their cells. Organelles are internal structures that perform a wide range of tasks, including energy generation and protein synthesis. Examples – The cells found in the organisms of Kingdom Protista, Fungi, Plantae and Animalia of the five kingdom classification scheme.

Note:
Individual components with specialised activities that are required to carry out life's operations make up the cell structure. The cell wall, cell membrane, cytoplasm, nucleus, and cell organelles are among these components. Prokaryotic and Eukaryotic cells are the two types of cells. Animal and Plant cells can both be Eukaryotic cells. All cells have the basic role of forming metabolic reaction sites.
