A diploid living organism develops from zygote undergoes which type of repeated cell division?

Options

A. Meiosis
B. Amitosis
C. Mitosis
D. Segmentation

Answer

To answer the question about the type of repeated cell division a diploid living organism undergoes after developing from a zygote, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Zygote**:
- A zygote is the initial cell formed when a sperm cell fertilizes an egg cell. It is a diploid cell, meaning it contains two sets of chromosomes, one from each parent.

2. **Types of Cell Division**:
- There are two main types of cell division:
- **Mitosis**: This is the process of cell division that results in two identical daughter cells, each having the same number of chromosomes as the parent cell. It is responsible for growth and repair in multicellular organisms.
- **Meiosis**: This type of cell division reduces the chromosome number by half and is involved in the production of gametes (sperm and egg cells).
- **Ermitosis**: This is a less common form of cell division that is not typically associated with the development of multicellular organisms.
- **Segmentation**: This refers to the division of an organism's body into repetitive segments, but it is not a type of cell division.

3. **Identifying the Correct Type of Cell Division**:
- Since the question asks about the repeated cell division that occurs after the zygote stage in a diploid organism, we focus on mitosis.
- Mitosis is the type of division that allows the zygote to grow and develop into a multicellular organism by producing more diploid cells.

4. **Conclusion**:
- Therefore, the correct answer is that a diploid living organism developed from a zygote undergoes **mitosis** as its repeated cell division.

### Final Answer:
A diploid living organism that develops from a zygote undergoes **mitosis**.
