Join us in this BioSpeak episode as we take a look at the structure and essential functions of the plasma membrane, also known as the cell membrane. We discuss its role as a semi-permeable barrier that protects cells and facilitates transport, signaling, and communication with the environment. Learn about the composition of the plasma membrane, including phospholipids, cholesterol, proteins, and saccharides, and how they work together to maintain cell integrity and function. Discover the mechanisms of passive and active transport that regulate molecular movement, and understand how saccharides act as identity tags for cells in immune responses. We also explore the role of plasmodesmata in plant cells for substance exchange and communication.
