The surface area/volume ratio is an important factor for one celled organisms. As a cell's volume grows, its surface area/volume ratio decreases, making it harder and harder to acquire enough nutrients via diffusion. Because of this, cells stop growing after reaching a certain size. After reaching this state, a one celled organism is likely to
A) enter into a spore state
B)continue to grow until it is so big it burst
C)use mitosis to diced and create daughter cells
D)stop eating that it shrinks and it’s surface area/volume ratio grows

Mitosis refers to a cell division in which a parent cell divides to give rise to two equal daughter cells. It helps in the growth and repair of tissues in multicellular organisms.

Once the cell has increased its size significantly, it undergoes mitosis to divide into smaller daughter cells.

It increases the area to volume ratio of the cell and helps the cell to get nutrition from a simple process such as diffusion.
