The main functions of mitosis are growth and repair. Some cells once fully formed do not undergo cell division, such as nerve cells and muscle cells. Since you can never re-grow or repair these types of cells once they are mature, you must take care of the ones you have.
Mark as brainliest, if you don't its ok:)
Glad I could help

Answer:
The human impact on the Amazon rainforest has been grossly underestimated according to an international team of researchers. They found that selective logging and surface wildfires can result in an annual loss of 54 billion tons of carbon from the Brazilian Amazon, increasing greenhouse gas emissions.

Answer:
It has physically increased in size. Often, growth of a multicellular organism occurs as more cells are created. In unicellular organisms (like bacteria), growth still occurs. ... For this reason, most biologists will tell you that development only occurs in multicellular organisms, not in unicellular ones.
The Nucleus contains all the genetic material, such as chromosomes and DNA, in a eukaryotic cell. It is the "command center" of a cell as it controls them. They are found in both Animal and Plant Cells.
Vacuoles provide structural support to a cell by regulating pressure. They also help with storage, waste disposal (vesicles also help with this), protection, and growth inside a cell. Vacuoles are only in Plant Cells, whereas Vesicles can be found in both.
The Cytoskeleton gives a cell its shape, especially ones that do not contain a cell wall. They also allow for cell movement, and enable organelles to move inside a cell. Only Animal Cells contain a Cytoskeleton as plants cells have a cell wall.
The main function of Centrioles is to help with cell division in Animal Cells. (during mitosis and meiosis).
