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).

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.

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 small cell will have a larger surface-to-volume ratio.

The surface area to volume ratio will increase

As the cell gets bigger, the surface to volume ratio gets smaller.

The surface area to volume ratio increases when a cell divides into two smaller cells. This is important for efficient nutrient exchange and waste removal as the cell size decreases.

False. A smaller cell has a higher ratio of surface area to volume, making moving the amount of required nutrients simpler.

As a cell grows, its volume increases faster than its surface area, leading to a decrease in the surface-to-volume ratio. This can limit the efficiency of nutrient exchange and waste removal across the cell membrane, potentially affecting the cell's ability to function optimally. In order to maintain a favorable surface-to-volume ratio, cells may undergo division or develop specialized structures.

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.
