Mitotic division is seen in diploid somatic cells
Exp. - embryo development
In this all somatic cells are formed through mitosis

In animal cells, the mitotic division is seen in Diploid somatic cells.

Mitosis is a type of cell division that occurs in eukaryotic cells, including animal cells. It is responsible for the growth, development, and maintenance of multicellular organisms. Mitosis results in the formation of two genetically identical daughter cells from a single parent cell. These daughter cells have the same number of chromosomes as the parent cell and are therefore diploid.

Here is a detailed explanation of why the correct answer is option C - Diploid somatic cells:

1. Mitosis and cell division:
- Mitosis is a part of the cell cycle, which includes several stages such as interphase, prophase, metaphase, anaphase, and telophase.
- During interphase, the cell prepares for division by growing, replicating its DNA, and synthesizing proteins.
- In prophase, the chromosomes condense and become visible. The nuclear envelope breaks down, and the spindle fibers begin to form.
- In metaphase, the chromosomes align at the cell's equator, and the spindle fibers attach to the centromeres of the chromosomes.
- In anaphase, the sister chromatids separate and move towards opposite poles of the cell.
- In telophase, the chromosomes reach the poles, the nuclear envelope reforms, and the cell begins to divide.
- Finally, cytokinesis occurs, dividing the cytoplasm and forming two daughter cells.

2. Diploid somatic cells:
- Diploid cells have two sets of chromosomes, one set inherited from each parent. In humans, somatic cells are diploid.
- Somatic cells are non-reproductive cells that make up the majority of an organism's body tissues and organs.
- Examples of somatic cells include skin cells, muscle cells, and nerve cells.
- These cells undergo mitotic division to replace damaged or worn-out cells, promote growth, and maintain the body's functions.

3. Haploid cells:
- Haploid cells have only one set of chromosomes and are typically involved in sexual reproduction.
- In animals, haploid cells are found in the reproductive organs, such as the testes and ovaries.
- Haploid cells are involved in the formation of gametes (sperm and egg cells) through a specialized cell division called meiosis.

Therefore, the correct answer is option C - Diploid somatic cells, as mitotic division occurs in these cells to ensure growth, repair, and maintenance of the organism's body.
