Cells communicate through a process called cell signaling. This involves various mechanisms, including the release of signaling molecules that bind to specific receptors on target cells. These interactions initiate a cascade of cellular responses, enabling cells to relay information about their environment or coordinate responses to stimuli. Hormones, neurotransmitters, and growth factors are essential in conveying messages between cells, ensuring proper functioning of biological systems. Efficient cell communication is fundamental for processes like development, immune response, and homeostasis.
