Detailed explanation-1: -In general, small size is necessary for all cells, whether prokaryotic or eukaryotic.
Detailed explanation-2: -Answer: The surface area to volume ratio (SA:V) limits cell size because the bigger the cell gets, the less surface area it has for its size.
Detailed explanation-3: -Seeing that the surface area to volume ratio of cells generally decreases as cells get larger, making the exchange of resources, waster and heat more and more difficult.
Detailed explanation-4: -Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.
Detailed explanation-5: -Cells are limited in size by their surface area to volume ratio. That is, their plasma membrane (surface area) must be large enough to import nutrients and excrete wastes for the entire cytoplasm (volume) of the cell. As cells get larger, their surface area to volume ratio increases, which is why cells are very small.
