In animals mitotic cell division is only seen in

Options

A. Haploid somatic cell
B. Diploid somatic cell
C. Diploid meiocytes
D. 1 and 3

Answer

To answer the question "In animals mitotic cell division is only seen in," we need to analyze the options provided: haploid somatic cell, diploid somatic cell, diploid meocytes, and the combination of options 1 and 3.

### Step-by-Step Solution:

1. **Understanding Mitotic Cell Division**:
- Mitotic cell division is a process where a single parent cell divides to produce two identical daughter cells. This process maintains the chromosome number of the parent cell in the daughter cells.

2. **Identifying the Types of Cells**:
- **Haploid Somatic Cells**: These cells contain only one set of chromosomes. In animals, somatic cells are typically diploid, meaning they have two sets of chromosomes.
- **Diploid Somatic Cells**: These cells contain two sets of chromosomes. In animals, most somatic cells are diploid and undergo mitosis.
- **Diploid Meocytes**: These are specialized cells that undergo meiosis to form gametes. They do not typically undergo mitosis.

3. **Analyzing Each Option**:
- **Option 1: Haploid Somatic Cell**: Incorrect, as mitotic division is not seen in haploid somatic cells in animals.
- **Option 2: Diploid Somatic Cell**: Correct, as mitotic division occurs in diploid somatic cells.
- **Option 3: Diploid Meocytes**: Incorrect, as these cells undergo meiosis, not mitosis.
- **Option 4: 1 and 3**: Incorrect, as both options 1 and 3 are wrong.

4. **Conclusion**:
- The only correct answer is **Diploid Somatic Cells**. Mitotic cell division in animals is primarily observed in these cells.

### Final Answer:
In animals, mitotic cell division is only seen in **Diploid Somatic Cells**.
