By which process cell repair in our body?
VerifiedAnswer: Mitosis
Explanation:
Mitosis is the fundamental process through which our body repairs damaged cells and replaces worn-out tissues. This remarkable cellular process ensures that when cells are injured, diseased, or naturally reach the end of their lifespan, new identical cells are produced to take their place.
During mitosis, a single parent cell divides to produce two genetically identical daughter cells. This process is crucial for maintaining healthy tissues throughout our body. When you get a cut on your skin, for example, the cells around the wound undergo mitosis to create new skin cells that fill in the gap and heal the injury.
The mitotic process occurs in several organized phases. First, the cell prepares by duplicating its DNA and organelles. Then, during the actual division phases - prophase, metaphase, anaphase, and telophase - the duplicated chromosomes are carefully separated and distributed equally between the two new cells. This ensures that each daughter cell receives exactly the same genetic information as the original cell.
Cell repair through mitosis happens continuously in various parts of our body. Your skin cells are constantly being replaced through this process, which is why minor scratches and cuts heal naturally. Similarly, the lining of your digestive system, blood cells, and many other tissues regularly undergo mitotic division to maintain proper function and repair damage.
What makes mitosis so important for repair is that it produces cells that are identical to the original healthy cells. This means the new cells can perform exactly the same functions as the ones they're replacing, maintaining the proper structure and function of tissues and organs. Without this process, our bodies would not be able to heal from injuries or replace the millions of cells that naturally die each day.
