Why is the surface area and volume important for cell sizes?

Answer 1

All contact between a cell and its environment takes place through its surface area. That is where food enters the cell. Oxygen enters the cell. The cell interacts with pathogens. The cell gets rid of wastes. It all happens at the surface area. A muscle cell works by lengthening and decreasing the size of its surface area.

Answer 2

Surface area is important for the exchange of materials, such as nutrients and waste products, with the environment, while volume determines the cell's metabolic activity and energy requirements. Cells need a high surface area-to-volume ratio to efficiently perform these functions and maintain homeostasis. If a cell becomes too large, its surface area-to-volume ratio decreases, making it difficult to meet its metabolic needs.

Answer 3

surface area to volume ratio is very critical to a cell.

a large surface area to volume ratio means that a cell can exchange materials with its surroundings more effectively.

for example, the RBCs of mammals have a circular biconcave shape which helps in increasing the surface o volume ratio. this helps it in easy exchange of gases with other cells cells in various tissues.

this aspect is not just important at the cellular level, but even for large organisms. animals in the polar regions are usually huge (especially homeotherms) because this reduces the surface to volume ratio, which helps the organism to maintain a higher body temperature. if the surface to volume ratio of an organism is more, more heat will be lost from the body, which is very harmful to the polar organisms. but such a body structure is found in desert animals, which need to lose more amount of heat in order to maintain optimum body temperature. :)

Answer 4

The materials entering or leaving a cell need to pass through the cell surface.

Answer 5

The number of reactions increase as the volume of metabolic volume within a cell increases. (The larger the volume the larger the number of reactions)

Answer 6

which is more critical to maintaining life processes surface area or volume

Answer 7

All chemical reactions take place on surfaces = so very important
