Why is cell signaling important?

This is necessary to communicate with other cells. See below


If cells don't signal to each other, no information is spread among the cells in the surrounding.

Take for example the human defence system. To recognize different viruses, the viral proteins are "stored" in the body. In this large and difficult system, cells must exchange information about these viral proteins.

Sometime signals (cytokines) are released by a cell to activate another cell to take a certain action. This could be anything and differs from cell to cell.

See it like you have a bunch of people in a building that is burning. The once that stand closest to the fire will signal to the others warning for the fire. If there is no signalling, the others aren't warned on time.
