Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following explains why a cell has to divide?
A
volume increases
B
surface area decreases
C
it will starve
D
it will die from cytoplasm poisoning
Explanation: 

Detailed explanation-1: -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-2: -For instance, when normal cells grown in a dish are crowded by neighbors on all sides, they will no longer divide.

Detailed explanation-3: -So if a cell grows larger instead of dividing, diffusion will be too slow and the cell will not be able to obtain nutrients and get rid of wastes efficiently, which ultimately would kill the cell. Thus, cells divide so that an organism can get bigger, despite the fact that cell size is limited.
