The type of division responsible for the growth of multiceullular organisms-

Answer

**Step-by-Step Text Solution:**

1. **Understanding Cell Division**: Cell division is the process by which a parent cell divides into two or more daughter cells. It is essential for growth, development, and repair in multicellular organisms.

2. **Types of Cell Division**: There are two main types of cell division: mitosis and meiosis. Each serves different purposes in the life cycle of an organism.

3. **Mitosis**: Mitosis is known as equational division. It is the type of cell division that results in two daughter cells that are genetically identical to the parent cell. Mitosis occurs in somatic (body) cells and is primarily responsible for growth and repair.

4. **Meiosis**: Meiosis is a different type of cell division that occurs in the formation of gametes (sperm and egg cells). It consists of two rounds of division (meiosis I and meiosis II) and reduces the chromosome number by half, making it a reductional division.

5. **Conclusion**: For the growth of multicellular organisms, mitosis is the type of cell division that is primarily responsible. It allows for the increase in cell number and the growth of tissues.

**Final Answer**: The type of division responsible for the growth of multicellular organisms is mitosis.
