Answer: As a cell's volume grows its membrane needs more and more surface area to bring nutrients oxygen and water into the cell and move waste out. The cell's surface area-to-volume ratio shows how much area is available to move materials in and out of the cell compared to the cell's volume. Cell Bio Lecture 21
1.C. Why is a cell's surface area-to-volume ratio important? Human Biology Final Exam

The surface -area- to -volume ratio also called the surface -to-volume ratio and variously denoted sa/vol or SA:V is the amount of surface area per unit volume of an object or collection of objects. In chemical reactions involving a solid material the surface area to volume ratio is an important factor for the reactivity that is the rate at which the chemical reaction will proceed.

The surface area to volume ratio of an object is the relationship between two measurements. It is the ratio of Surface area to volume. It shows the comparison between the size of the outside of an object and the amount inside. Small or thin objects have a large surface area compared to the volume. This gives them a large ratio of surface to volume.

Structure. Microvilli are covered in plasma membrane which encloses cytoplasm and microfilaments.Though these are cellular extensions there are little or no cellular organelles present in the microvilli.. Each microvillus has a dense bundle of cross-linked actin filaments which serves as its structural core. 20 to 30 tightly bundled actin filaments are cross-linked by bundling proteins ...

In the biological context of organisms' production of gene products downregulation is the process by which a cell decreases the quantity of a cellular component such as RNA or protein in response to an external stimulus.The complem...
