What else can I help you with?
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.
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.
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?
Most cells are small because a larger surface area-to-volume ratio allows for more efficient nutrient exchange and waste removal. This helps the cell maintain homeostasis by ensuring its internal environment remains stable. Additionally, smaller cells can divide and replicate more easily than larger cells.
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.
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.
