The surface area to volume ratio decreases - assuming the shape remains similar.
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 larger the surface area to volume ratio of a cell, the smaller its size (and vice versa).
As size increases, the s/v ratio decreases-- the s/v ratio of a cubic cell 1mm on a side is 6, but the s/v ratio of a cubic cell 3mm on a side is only 2.
A smaller cell has a higher surface area to volume ratio. A reason for this is volume is cubic (3D) and surface area is 2D so when surface area increases a little bit, the volume increases exponentially. And when the surface area shrinks a little bit, the volume decreases exponentially.
A small cell will have a larger surface-to-volume ratio.
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.
As the cell gets bigger, the surface to volume ratio gets smaller.
As the cell gets bigger, the surface to volume ratio gets smaller.
As the cell gets bigger, the surface to volume ratio gets smaller.
If a surface area:volume ratio gets too small, then it is difficult for the cell to absorb/expell substances, and substances must travel a long way to exit or leave the cell. This means that a cell will want a large surface area:volume ratio. However, the surface area:volume ratio decreases as a cell expands. Because of this, a cell will reach a certain point where expanding any more will cause the cell to become inefficient due to its low surface:area to volume ratio. Therefore, cells are limited by the efficiency of their ratio; they will not grow to a size where their ratio becomes too inefficient.
The larger the surface area to volume ratio of a cell, the smaller its size (and vice versa).
The surface area to volume ratio will increase
As the cell gets bigger, the surface to volume ratio gets smaller.
Lenght to width
False. A smaller cell has a higher ratio of surface area to volume, making moving the amount of required nutrients simpler.
The larger a cell becomes, the more demands it places on its DNA . It also becomes more difficult for the cell to move nutrients and oxygen in, and waste products out. The ratio of surface area to volume becomes too small.
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.
