Surface Area to Volume Ratio

Definition

The surface area to volume ratio is a relationship that describes how much surface area an object (like a cell) has compared to its volume. As the size of an object increases, its volume grows faster than its surface area.

Related terms

Cell Size:

The dimensions or magnitude of a cell. It's important because it affects how efficiently materials can move in and out of cells.

Diffusion:

The process by which molecules spread from areas of high concentration to areas of low concentration. This is one way cells get necessary nutrients and expel waste.

Homeostasis:

The state of steady internal conditions maintained by living things. Cells need to maintain homeostasis for optimal function, and efficient nutrient/waste exchange plays a big part in this.
