Explanation:

Question 3: What is the purpose of Mitosis in an organism?

Mitosis is a type of cell division. Its main purposes include growth of the organism (as cells divide to increase the number of cells in tissues and organs during development), repair of damaged tissues (replacing old or injured cells with new ones), and asexual reproduction in some organisms (like single - celled eukaryotes or some plants, where mitosis produces new individuals). It ensures that the daughter cells have the same genetic material as the parent cell, maintaining genetic stability in somatic (body) cells.

• End Result: Mitosis results in the formation of two daughter cells. These daughter cells are genetically identical to the parent cell and to each other. Each daughter cell has the same number of chromosomes as the parent cell (in diploid organisms, they remain diploid).
• Cells Doing Mitosis the Most: Cells that are involved in rapid growth or frequent repair tend to undergo mitosis the most. For example, skin cells are constantly being replaced as they are exposed to the environment and get damaged or shed. Hair follicle cells, cells in the lining of the digestive tract, and bone marrow cells (which produce blood cells) also undergo mitosis frequently.
• Cells Doing Mitosis the Least: Cells that are highly specialized and have lost the ability to divide or divide very rarely. Nerve cells (neurons) are a prime example. Once they mature, they generally do not undergo mitosis. Muscle cells, especially cardiac muscle cells and most skeletal muscle cells in adults, also undergo mitosis very rarely.

Answer:

The purpose of mitosis in an organism is for growth (increasing the number of cells during development), repair (replacing damaged or old cells), and asexual reproduction (in some organisms). It also ensures that daughter cells have the same genetic makeup as the parent cell, maintaining genetic stability in somatic cells.
