I just learned about this in school. They need to be small in the ratio to make them more efficent in having molecules enter and leave them quickley.

How will surface area to volume ratios of a small cell compare to those of a large cell?
A small cell will have a larger surface-to-volume ratio.
Is the surface-area-to-volume ratio of a small cell less than that of a larger cell?
As a cell becomes larger the surface area to volume ratio gets smaller. The volume increases by the square of the surface area. That is the main reason that one celled organisms are small.
How does surface area to volume ratio affects an organism?
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
Is true that small cells have larger surface area to volume rations than do larger cells?
Cell have a greater surface area to volume rations than a larger cell.
How does a small surface area per unit volume help cacti live in areas that are dry for long periods of time?
Any living thing that has a low surface area per unit of volume will lose less moisture to evaporation than a living thing with a high surface area to volume ratio.
What limits most cells to a small size?
The surface area-to-volume ratio of the cell.
Cells are limited in size by their surface Ares and what else?
Cell size is limited by volume.Surface area to volume ratio (surface area / volume)Nucleo-cytoplasmic ratioFragility of cell membraneMechanical structures necessary to hold the cell together (and the contents of the cell in place)
Why are small cells better then large cells for moving materials through membranes?
small cells have a greater surface-to-volume ratio than larger cells.
What Limits Most Cells to a Very Small Cell?
The surface area-to-volume ratio of the cell.
Why are groups of a small cells better than one large cell at moving material in and out?
they have a greater surface-to-volume ratio
Why can small cells exchange subtances more readily than large cells?
Small cells have higher surface area to volume ratio than larger cells.
Why would a group of small cells help an organism maintain homeostasis better than one large cell?
The group of small cells would have a greater surface area-to-volume ratio, so are able to exchange materials with their surroundings more efficiently.
What ratio increases when a cell divides into smaller cells?
You are probably thinking of the surface area to volume ratio. When you have two small cells instead of one big one, there is more 'outside'.
Why are groups at small cells better than one large cell at moving material in and out?
They have a greater surface-to-volume ratio
Why are groups of small cells better than one large cell material in and out?
They have a greater surface-to-volume ratio. :)
Explain why most cells are small?
It has to do with the surface area to volume ratio. The cell interacts with its environment at the cell surface. If a cells volume is too large the surface area isn't sufficient to exchange the necessary oxygen/nutrients/wastes to maintain the functions of a cell.
Why are metabolically active cells limited to very small sizes?
They are more metabolically acitve then larger cells because they have a smaller surface area to volume ratio then the larger cells which means the enzymes and proteins can move around faster and this makes the cell metabolically active.
