because it has the surface area of volume
Cell have a greater surface area to volume rations than a larger cell.
Larger cells will have a greater surface area-to-volume.
If the smaller cells' total volume is at least that of the larger cell then the smaller cells have the greater surface area.
small cells have a greater surface-to-volume ratio than larger cells.
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.
Small cells have higher surface area to volume ratio than larger cells.
When cells get smaller, the volume (as well as mass) decreases faster than the surface area so the surface:volume increases. Cells with a high surface:volume are more effective in receiving nutrients through diffusion. A cell (assume perfect sphere) with radius 2 has a surface area of 16pi and volume of 32pi/3. A cell with radius 3 has a surface area of 36pi and volume of 108pi/3. Also relatively speaking, volume can be thought of as y=x3 and surface area as y=x2. When there is a change in x, the change is more dramatic in the volume, so small cells have high ratios and large cells have low ratios.
they have a greater surface-to-volume ratio
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.
surface area/ volume. wider range of surface area to volume is better for cells.
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.
B has smaller cells but more surface area than A.
