DIFFERENTIATED CELL

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is one reason the cell divides?
A
Too much information for the nucleus to process
B
Because it’s lonely
C
Too big for materials to move around the cell efficiently
D
None of the above
Explanation: 

Detailed explanation-1: -If the cell grows too large, the plasma membrane will not have sufficient surface area to support the rate of diffusion required for the increased volume. In other words, as a cell grows, it becomes less efficient.

Detailed explanation-2: -If a cell grows larger, then the volume increases much more rapidly than the surface area, causing the ratio of surface area to volume to decrease. The problem is that the cell would not be able to get enough oxygen and nutrients in and get the waste products out.

Detailed explanation-3: -1. The larger the cell, the more demands the cell places on its DNA. 2. The cell has trouble moving enough nutrients and wastes across the cell membrane.

Detailed explanation-4: -Cells are so small because they are easier to replace, and a cell needs to be small to be able to perform the tasks a cell needs to do. If cells were bigger it would be harder for the body to replace the cell without disrupting what is going on in the body and delaying a process.
