This video tutorial covers the cell membrane, also known as the plasma membrane, and its crucial role in maintaining homeostasis by protecting the cell and regulating the internal environment. It delves into the structure of the cell membrane, focusing on the phospholipid bilayer and the fluid mosaic model. The tutorial also highlights the four key components of the cell membrane: phospholipids, proteins, carbohydrates, and cholesterol, explaining their functions. Finally, it discusses the concept of selective permeability, which allows certain molecules to pass through the membrane while restricting others.
