Cell size
Cell size refers to the physical dimensions of a cell, which can vary greatly among different types of organisms. It’s typically measured in micrometers (millionths of a meter). Cells can be very small, like bacteria, or larger, like certain animal and plant cells. The size influences how efficiently a cell can perform essential functions such as nutrient intake, waste removal, and communication within the organism. Generally, smaller cells have a larger surface area relative to their volume, which helps them exchange materials more effectively. Cell size is important for understanding how cells grow, divide, and carry out their roles in living organisms.
