Mitosis, metabolism, and communication are essential cellular processes for growth, repair, and maintaining homeostasis.
Mitosis: Mitosis is a process where cells divide to produce new cells for growth and healing, ensuring the replacement of worn-out cells, such as in skin injuries. It is crucial for maintenance and repair in multicellular organisms.
Metabolism: Cells require a steady supply of energy from metabolism to perform various functions like assembling proteins, releasing chemical signals, and laying down bone material. Metabolism is essential for the synthesis, breakdown, and transportation of molecules within cells.
Communication: Cells communicate through the release of chemical signals to warn of infections, laying down pheromones, and responding to hormones. Communication plays a vital role in coordinating cellular activities and maintaining homeostasis.
