Cell physiology is the study of the functions and processes that occur within cells, the basic units of life. It examines how cells maintain homeostasis, communicate with each other, and respond to their environment. Key processes include metabolism, cell signaling, and transport mechanisms, which help cells obtain nutrients, remove waste, and regulate internal conditions. Understanding cell physiology is essential for comprehending how tissues and organs function in living organisms. It also provides insights into various biological processes, such as cell division, growth, and differentiation. This knowledge is crucial for fields like medicine, biotechnology, and pharmacology, where it aids in developing treatments for diseases.
