Mitosis is important for skin, gut and blood cells because-

Options

A. It allows the animals to grow faster
B. All cells must divide
C. Old and work out cells are regularly replaced
D. It helps the cells to overcome the effect of UV-rays

Answer

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two daughter cells that are genetically identical to the parent cell. This process is crucial for growth, repair, and maintenance of tissues.

2. **Equational Division**: Mitosis is often referred to as an equational division because it maintains the chromosome number. For example, if the parent cell is diploid (2N), the daughter cells will also be diploid (2N). This ensures that the genetic information is preserved.

3. **Clonal Replication**: The daughter cells produced by mitosis are clones of the mother cell. This means they have the same genetic material, which is essential for the proper functioning of tissues like skin, gut, and blood.

4. **Tissue Maintenance**: Skin, gut, and blood cells are constantly being worn out or damaged due to their exposure to various environmental factors and their roles in the body. Mitosis allows for the replacement of these old or damaged cells with new, healthy cells.

5. **Function of Mitosis**: The primary function of mitosis in these tissues is to ensure that there is a continuous supply of cells to replace the old ones. This is vital for maintaining the integrity and functionality of the skin, gut lining, and blood supply.

### Final Answer:
Mitosis is important for skin, gut, and blood cells because it allows for the replacement of old or damaged cells with new, genetically identical cells. This process ensures that these tissues can maintain their structure and function effectively.
