because it has the surface area of volume
What else can I help you with?
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.
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.
Which statements about the ratio of cell surface area to cell volume is are correct?
As cell volume increases, the ratio of cell surface area to cell volume decreases. This is because the surface area increases by a square factor while the volume increases by a cube factor. A higher surface area to volume ratio is more favorable for efficient nutrient exchange and waste removal in cells.
Which 2 things must be compared to explain why almost all cells are small?
The surface area to volume ratio of cells must be compared to explain why almost all cells are small. As cells grow larger, their volume increases faster than their surface area, leading to inefficiencies in nutrient and waste exchange. Smaller cells have a higher surface area to volume ratio, allowing for more efficient cellular processes.
What happens the surface to volume ratio when the cell becomes larger?
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.
Why can small cells exchange substances more readily than large cells?
Small cells have a higher surface area to volume ratio, which allows for a more efficient exchange of substances with their environment. This is because the surface area of a cell determines the rate at which substances can be exchanged, and smaller cells have a greater surface area relative to their volume compared to 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.
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.
Which cell has the fastest rate of diffusion across the surface?
Cells with a larger surface area-to-volume ratio, such as small cells like bacteria or single-celled organisms, will typically have a faster rate of diffusion across the surface. This is because a larger surface area allows for more space for molecules to diffuse in and out of the cell more efficiently.
