Cell Organelles and Their Functions

The video explores the essential components of cells, focusing on the cell membrane, cytoplasm, and cytoskeleton. It explains how the cell membrane protects and regulates the cell's interaction with its environment, the cytoplasm's role in housing organelles and facilitating biochemical processes, and the cytoskeleton's function in maintaining cell shape and enabling movement. The video also highlights the importance of these organelles working together to keep cells alive.
