How is the shape and size of cells related to its function?

Dear student, Cell shape is related to its function. It can be explained by taking the example of nerve cell which is long and this helps it to carry information from one part of the body to another.  White blood cells and Amoeba do not have a definitive shape; their cells have the ability to change their shape. For example, Amoeba keeps on changing its shape by producing various projections across its cell surface, which is called pseudopodia. These projections help the Amoeba in feeding and moving. This helps the white blood cells in capturing infectious microorganisms in the body. smaller cell is more effective and transporting materials, including waste products, than a larger cell. smooth muscle cells due to spindle shape help in muscle contraction and relaxation.
