Plasma membrane: the security guard of the cell

The video explains the cell membrane's role as a security guard, controlling what enters and exits the cell. It describes the membrane's structure, including the phospholipid bilayer, cholesterol, and proteins. The fluid nature of the membrane allows flexibility, crucial for cell function. Transport mechanisms, both passive and active, are discussed, along with endocytosis and exocytosis processes. The video also covers how viruses exploit cell receptors to enter cells, highlighting the importance of the membrane in maintaining cell health.
