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 is the relationship between the surface area to volume ratio of a cell and its size?
The larger the surface area to volume ratio of a cell, the smaller its size (and vice versa).
What is the relationship between the length of a side and the surface area-to-volume ratio of a cell?
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.
Which cell has the greater surface area compared to its volume the large cell or one of the smaller cells?
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.
How will surface area to volume ratios of a small cell compare to those of a large cell?
A small cell will have a larger surface-to-volume ratio.

How does surface to volume ratio to the size of a cell?
As the cell gets bigger, the surface to volume ratio gets smaller.
How does surface-to-volume ratio relate to the size of the cell?
As the cell gets bigger, the surface to volume ratio gets smaller.
What is the relationship between the surface area to volume ratio of a cell and its size?
The larger the surface area to volume ratio of a cell, the smaller its size (and vice versa).
how does surface to volume relate to the size of a cell?
As the cell gets bigger, the surface to volume ratio gets smaller.
What ratio increases when a cell divides into two smaller cells?
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.
True or False The smaller a cell is the more difficult it is for the cell to move enough materials across its cell membrane?
False. A smaller cell has a higher ratio of surface area to volume, making moving the amount of required nutrients simpler.
What effect does cell size have on a cell's ability to efficiently carry out its activities?
The larger a cell is, the more difficult it becomes for nutrients and waste to move across the cell membrane efficiently. This can hinder the cell's ability to carry out metabolic activities effectively. Smaller cells have a higher surface area-to-volume ratio, allowing for easier exchange of materials.
How does surface volume ratio relate to a limit on cell expansion?
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.
Why is it helpful for cells to divide?
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.
How does surface to volume ratio relate to the size of a cell?
As the cell gets bigger, the surface to volume ratio gets smaller.
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.
