Cell Division - Reasons for Cell Division

Question 1

Reasons for cell division

Answer 1

• DNA overload:​
• The cell becomes too large for the DNA to handle.
• There is only enough DNA to regulate a cell of a certain size.
• Exchange rate of materials:​
• Food and water enter a cell and waste products leave - through the cell membrane.
• This rate of exchange is dependent on the cell’s surface area to volume ratio.​
• As something becomes bigger the surface area of the cell gets smaller in respect to the size.
