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.
The 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.
Surface ratio is squared while the volume ratio is cubed.
Larger cells will have a greater surface area-to-volume.
they have a greater surface-to-volume ratio
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.
It will decrease. In a larger cell, you have less surface area per volume.
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.
The Volume increases faster than the Surface Area
They grow
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.
The surface area to volume ratio will increase
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.
As the cell grows larger the ratio of surface area to volume increases. Larger cell = more volume for the amount surface area.
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.
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.
really.. the answer is that the volume also gets 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.

Cell have a greater surface area to volume rations than a larger cell.
