How does the structure of a cell relate to its function?
A cell's structure and function are related to one another. The shape and size of a cell, help determine its specific function in our body. For example, the structure of the nerve cell is long and thin because it functions to relay electrical messages all over the body.
How does the structure affect function?
In biology, a key idea is that structure determines function. In other words, the way something is arranged enables it to play its role and fulfill its job within an organism (a living thing). Structure-function relationships arise through the process of natural selection.
