THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following explains why a cell’s size is limited?
A
volume increases faster than surface area
B
surface area increases faster than volume
C
homeostasis is disrupted by a cell that is too large
D
both a and c are correct
Explanation: 

Detailed explanation-1: -The size of a cell is limited by the relationship of the cell’s outer surface area to its volume or its surface area-to-volume ratio . Thus, the correct answer is option A. Was this answer helpful?

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Why don’t cells just keep getting bigger instead of multiplying? Cells are limited in size because the outside (the plasma membrane) must transport food and oxygen to the inside of the cell. This can be represented by what is known as the surface to volume ratio .

Detailed explanation-5: -When a cell’s volume grows too large, it cannot exchange enough nutrients and wastes to survive, and it must divide into two smaller cells that have more relative surface area.
