Cell processes refer to the various activities that occur within a cell to maintain life. These processes include metabolism, which involves chemical reactions that convert food into energy, and cell division, where a cell replicates to produce new cells. Other important processes are protein synthesis, where cells create proteins necessary for function, and cell signaling, which allows cells to communicate with each other. Additionally, cells perform transport processes to move substances in and out, such as diffusion and osmosis. These processes ensure that cells receive nutrients and expel waste. Overall, cell processes are essential for growth, repair, and overall cellular function.
