Question

Why are all cells very small? Explain what limits the size of cells

Answer 1

Answer: A cell has things that enter and exit it constantly. Since it has things leaving constantly and coming in constantly it can't get any bigger since everything that enters it leaves

Explanation: Hope this helps :)

Answer 2

Cell Size is governed by several factors: The size of the cell is controlled by metabolic requirements. DNA must be available to produce the enzymes and proteins needed for proper functioning. A too small cell will not have enough DNA to support life and a cell too large will need an enormous amount of DNA to carry on its functions. A second restriction involves surface area to volume ratio. As the cell increases in size, the volume increases geometrically while the surface area increases arithmetically. Eukaryotic cells cope with these problems in that they contain membrane bound organelles. These organelles break up the volume of the cell performing distinct functions which cuts down on the raw materials needed. Each part of the cell does not need the same material to function.
