There are two types of cell division. the first (a) produces cells that are identical to the original cell. the second (b) produces cells that are different from the original cell. which type of cell division do you think is responsible for these processes? replacement of damaged skin cells growth of an organism production of sperm and egg cells

Replacement of damaged skin cells: type A

Growth of an organism: type A

Production of sperm and egg cells: type B

Explanation:

The only cells that will undergo type B cell division are germ cells, because they are responsible for the production of gametes, which have half the amount of DNA that you can find in any other type of cell. The reason for this difference is that when two gametes merge during the process of fecundation, they combine both DNAs to generate one cell having the same amount of DNA as the somatic cells of a given organism. These new cell will give place to a new organism. If gametes had the same amount of DNA as somatic cells, every new organism that was born would have twice as much DNA as their parents.

For growth of an organism or replacement of a damaged tissue, like skin, your body needs to produce cells that are identical to the cells that divided to generate them, because these new cells will not participate in the process of fecundation, therefore, they will need the total amount of DNA and not only half of it.
