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.

∙ 13y agoThe ratio of surface area to volume increases.
The area of a sphere is proportional to its radius squared. Volume is proportional to radius cubed. As the radius increases, the volume increases more than the surface area. As the radius decreases, the volume decreases more than the surface area, so the ratio of surface area to volume 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.
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 happens when the size of body of organism increases and the body design becomes more complex?
Because the more complex an organism become the more surface area to volume ratio.This means that unlike simple organism(like insects) who rely on diffusion for transport of oxygen and nutrients is readily available due to their excellent surface area to volume ratio. However if an organism has a bad surface area to volume ratio(larger organisms) they require a more efficient flow of oxygen and nutrients throughout their body.
How does a cell's ratio of surface area to volume change as the cell grews large?
It will decrease. In a larger cell, you have less surface area per volume.
Why can a cell get only so large?
There is a surface area to volume ratio, as a cell gets larger it becomes harder and harder to transport materials inand out of the cell. There has to be enough surface area to supply the cell with all of the materials that it needs for survival.
As a cell becomes larger what happens to its surface area and volume?
The Volume increases faster than the Surface Area
What happens to surface area to volume ratios for larger and larger cubes?
They grow
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.
What happens to the surface area to volume ratio when folds are made in a cell's outer membrane?
The surface area to volume ratio will increase
Describe what happens to the surface area to volume ratio for larger and larger cubes?
For a cube with edge length, L. Surface area = 6L2. Volume = L3. So ratio of Surface Area / Volume = 6 / L. Therefore, as the side length, L, increases, the ratio will decrease.
How does a cell's ratio of surface area to volume change as the cell grows larger?
As the cell grows larger the ratio of surface area to volume increases. Larger cell = more volume for the amount surface area.
What does volume and surface area have in common?
The volume of a body and the surface area arerelated but not in a direct way. For a given volume, the smallest surface area of an object is seen then the object is a sphere. As the shape flattens from a sphere, so the surface area becomes larger. When the object approaches an infinitely small thickness, the surface area approaches and infinite size.
How does the ocean floor spreading affect the depth of the ocean?
Think o the volume of a box. As the base gets larger in perimeter, the surface area of the box becomes greater, and the volume increases.
What happens to the volume as an object gets larger?
really.. the answer is that the volume also gets larger
What happens to the volume and surface area of a cell as a cell becomes larger?
They both increase with increasing cell radius (if we model a cell as a sphere). However, the rate of increase of the surface area is in general slower (dA/dr = 8πr) compared to the rate of increase of the volume (dV/dr = 4πr2). This would mean that with increasing cell size, the surface area to volume ratio is becoming smaller and smaller, giving a cell less surface area for the transport of nutrients for a given unit volume.

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.
