I just learned about this in school. They need to be small in the ratio to make them more efficent in having molecules enter and leave them quickley.

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.
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.
How does surface area to volume ratio affects an organism?
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
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.
How does a small surface area per unit volume help cacti live in areas that are dry for long periods of time?
Any living thing that has a low surface area per unit of volume will lose less moisture to evaporation than a living thing with a high surface area to volume ratio.
What limits most cells to a small size?
The surface area-to-volume ratio of the cell.
Why are small cells better then large cells for moving materials through membranes?
small cells have a greater surface-to-volume ratio than larger cells.
What Limits Most Cells to a Very Small Cell?
The surface area-to-volume ratio of the cell.
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
Why can small cells exchange subtances more readily than large cells?
Small cells have higher surface area to volume ratio than larger cells.
Which 2 things must be compared to explain why almost all cells are small?
The surface area to volume ratio of cells must be compared to explain why almost all cells are small. As cells grow larger, their volume increases faster than their surface area, leading to inefficiencies in nutrient and waste exchange. Smaller cells have a higher surface area to volume ratio, allowing for more efficient cellular processes.
Why can small cells exchange substances more readily than large cells?
Small cells have a higher surface area to volume ratio, which allows for a more efficient exchange of substances with their environment. This is because the surface area of a cell determines the rate at which substances can be exchanged, and smaller cells have a greater surface area relative to their volume compared to larger cells.
What ratio increases when a cell divides into smaller cells?
You are probably thinking of the surface area to volume ratio. When you have two small cells instead of one big one, there is more 'outside'.
Why are groups of small cells better than one large cell material in and out?
Groups of small cells are better than one large cell because they have a higher surface area to volume ratio, enabling more efficient exchange of materials in and out of the cells. This increased surface area allows for faster diffusion of nutrients, gases, and waste products, leading to improved cellular functions. Additionally, small cells are more flexible and adaptable to changing environmental conditions.
Why are groups at small cells better than one large cell at moving material in and out?
They have a greater surface-to-volume ratio
Cells are limited in size by their surface Ares and what else?
Cells are also limited in size by their ability to effectively transport materials in and out of the cell. As a cell grows larger, the surface area to volume ratio decreases, making it harder for nutrients, oxygen, and waste to pass through the cell membrane efficiently. This can lead to issues with maintaining proper function and homeostasis within the cell.
Why are metabolically active cells limited to very small sizes?
Metabolically active cells are limited to small sizes because a large cell would struggle to efficiently transport nutrients and waste across its membrane. The surface area to volume ratio decreases as a cell gets larger, making it harder for molecules to move in and out of the cell to support metabolism. Therefore, small cells have a higher surface area to volume ratio, allowing for more effective exchange of nutrients and waste.
