The variety of cell shapes seen in prokaryotes and eukaryotes reflects the functions that each cell has, confirming the structure-function relationship seen throughout biology. Each cell type has evolved a shape that is best related to its function. For example, the neuron in Figure below has long, thin extensions ( axons and dendritres ) that reach out to other nerve cells. The extensions help the neuron pass chemical and electrical messages quickly through the body. The shape of the red blood cells ( erythrocytes ) enable these cells to easily move through capillaries . The spikes on the pollen grain help it stick to a pollinating insect or animal so that it can be transferred to and pollinate another flower. The long whip-like flagella (tails) of the algae Chlamydomonas help it swim in water.
