What is ratio of surface area to volume?
surface area/ volume. wider range of surface area to volume is better for cells.
Why do smaller cells have a greater surface area to volume ratio?
If the cells are spherical, the surface area increases as the square of the radius while the volume increases as the cube of the radius. Therefore, as the cells become larger, their volumes increase much more rapidly than their surface areas. Conversely, as the cells become smaller, their volumes decrease much more rapidly that their areas and so the surface area to volume increase. With non-spherical cells the calculations are much more complex, but the general pattern still applies.
What happens to the relationship between the surface area and volume of the cell as it gets larger?
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small. That may be the effect but the question as worded is purely arithmetical. Surface area is proportional to the square of the linear dimensions; volume to the cube.
The area of a cells outer surface in relationship to its volume is?
cell membrane
What happens to a cells surface area to volume ratio as it gets smaller?
It increases.
Which statements about the ratio of cell surface area to cell volume is are correct?
Larger cells will have a greater surface area-to-volume.
Which has the greater surface area one large cell or 27 smaller cells?
If the smaller cells' total volume is at least that of the larger cell then the smaller cells have the greater surface area.
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.
Why do cells get so big than divide?
Cells are dependent on the ration between surface area and volume. as the cels get bigger the ratio decreases, meaning that the volume gets larger faster than does the surface area. they cant survive past a certain point, because the nutrients that permeate the membrane have a harder time diffusing throughout a larger volume with a comparatively smaller surface area. this is why cells divide: the volume splits in half, but the surface area stays the same.
Why can small cells exchange subtances more readily than large cells?
Small cells have higher surface area to volume ratio than larger cells.
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
What is ratio of surface area to volume?
surface area/ volume. wider range of surface area to volume is better for cells.
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.

Therefore, as the cells become larger, their volumes increase much more rapidly than their surface areas.

Two models of cells are shown below. Why would model B be better for moving nutrients in and out of the cell?
B has smaller cells but more surface area than A.
What is the surface area to volume ratio?
surface area/ volume. wider range of surface area to volume is better for cells.
Cells are small because?
they need to fit in your body if they were bigger than they would not have room to fit in your body system...Cells are small because of the area around it and the volume. Cells are in the body.
