What are the 2 reasons why cells undergo the process of mitosis?
Cells divide for two reasons:
- Growth. We all started out as a single cell; the fusion of a sperm from dad and an egg from mom.
- Repair. Cells are constantly wearing out and getting damaged, and unless an organism replaces them at least as fast as they are lost, a gradual deterioration will occur.
What are two reasons that cells divide rather than continue to grow indefinitely?

| What are two reasons why cells divide rather than continue to grow indefinitely? | The larger a cell becomes… 1the more demans the cell places on its DNA 2the more trouble the cell has moving enough nutrients and wastes across the cell membrane |
What are two reasons that cells go through mitosis and what type of cells go through mitosis?
Cells can divide through mitosis to replace the worn out or dead cells in the body of living organism. Another reason why cell division is required and takes place can be to form the germ cells/gametes/sex cells(sperm and ovum).
What are the two main reasons why cell size is limited?
Cell size is limited by a cell’s surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes.
What are the 2 ways that cells know to stop dividing?
What are the 2 ways that cells “know” to stop dividing? Cells know to stop dividing when they are in contact with each other. This is called “contact inhibition.” The other way is that there are “go” and “no go” switches that are located along the path the cell takes. some it is when they reach maturity.
What are 3 reasons why cells divide?
Terms in this set (3)
- 1 growth. Go from one cell/( zygote to a trillion)
- 2 replace. Repair\ 50 million cells die second.
- 3 reproduction. ( make cells for reproduction make specialized sex cells)
What is a reason for cells to undergo mitosis?
Cells undergo mitosis in order to promote growth or to repair damage. As you get older and grow bigger, you need more cells, and so your cells undergo…
What are the 4 reasons for mitosis?
What Are Three Primary Purposes of Mitosis?
- Asexual Reproduction. In a single-celled organism, such as an amoeba, mitosis is how the cell reproduces.
- Growth. As plants and animals age, most also grow in size.
- Tissue Repair. When an organism is injured, mitosis occurs to replace the damaged cells.
- Errors in Mitosis.
Which is a reason why cells remain small?
Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Why do cells need to divide?
It is important for cells to divide so you can grow and so your cuts heal. It is also important for cells to stop dividing at the right time. If a cell can not stop dividing when it is supposed to stop, this can lead to a disease called cancer. Some cells, like skin cells, are constantly dividing.
What are the two main reasons that cells divide?
Cell divide because of the surface area to volume ratio. The surface area needs to be larger than the volume of cells for these processes to strive. Also to know is, what are the 2 main reasons cells divide? Two reasons that cells divide is because of meiosis and because of mitosis.
What is the best explanation for why cells are so small?
Answer Wiki. Cells are generally small in size because of two main reasons. Different regions of a cell can communicate with each other rapidly for the cell to function effectively.
Why are cells not able to increase in size?
Cells cannot, therefore increase beyond certain practical limits to two reasons; speed of diffusion and surface area / volume ratios. There is, actually, a way cells use to limit the effects of the surface area / volume ratio.
When do cells need to produce new cells?
Mitosis is involved in the production of new cells when the tissues of multicellular organisms are injured. It is also responsible for the regeneration of tissues by replacing the dead cells from new cells.
