Growth and repair of damaged tissue involve

Options

A. miotic cell divison only
B. both mitotic and meiotic cells divisions
C. meiotic cell division only
D. amitotic cell division only

Explanation

To answer the question "Growth and repair of damaged tissue involve," we need to understand the processes of cell division involved in these biological functions. Here’s a step-by-step solution:

### Step 1: Understand the Types of Cell Division
- **Mitosis** is a type of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell. It is essential for growth, repair, and asexual reproduction.
- **Meiosis** is a different type of cell division that reduces the chromosome number by half and is used in the formation of gametes (sperm and egg cells).

**Hint:** Remember that mitosis is for growth and repair, while meiosis is for reproduction.

### Step 2: Identify the Role of Mitosis in Growth and Repair
- Growth of tissues and the repair of damaged tissues primarily involve mitosis. When cells divide by mitosis, they produce new cells that replace damaged or lost cells, facilitating healing and growth.

**Hint:** Think of mitosis as the process that helps in replacing cells and repairing tissues.

### Step 3: Recognize the Importance of Somatic Cells
- Somatic cells are the body cells that undergo mitosis. These cells are responsible for growth and tissue repair. They maintain the same diploid number of chromosomes after division, which is crucial for the integrity of the tissue.

**Hint:** Somatic cells are the ones involved in growth and repair, not gametes.

### Step 4: Conclude the Answer
- Since the question specifically asks about the growth and repair of damaged tissue, the correct answer is that these processes involve **mitosis** and not meiosis.

**Hint:** Focus on the type of cell division that maintains the chromosome number for growth and repair.

### Final Answer:
The growth and repair of damaged tissue involve **mitosis**.
