Which best describes the importance of mitosis to living organisms
tresset_1 [31]

Answer:

Mitosis is a process of cell division that leads into formation of two daughter cells that are genetically identical to each other and to the original cell. So this is greatly important to living organisms because Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
