NEET BIOLOGY

Detailed explanation-1: -Answer: Significance of mitosis: It helps in maintaining the same number of chromosomes in daughter cells after division. It is responsible for growth and development of multicellular organisms. It helps in repairing of damaged tissues.

Detailed explanation-2: -Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information. The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.

Detailed explanation-3: -Each of these methods of cell division has special characteristics. One of the key differences in mitosis is a single cell divides into two cells that are replicas of each other and have the same number of chromosomes. This type of cell division is good for basic growth, repair, and maintenance.

Detailed explanation-4: -Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself. When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell.

Detailed explanation-5: -Cells also divide in order to replace damaged or worn-out cells. Most cell division produces genetically identical cells, meaning they have the same DNA. The process of mitosis, which ensures that each nucleus in each resulting cell after cell division is genetically identical, is essential to this process.
