It explains the generalized cell model, distinguishing cytoplasm, cytosol, and organelles, then details the plasma membrane as a selective barrier made of a phospholipid bilayer using the fluid mosaic model, including integral and peripheral proteins, cholesterol, hydrophilic heads, hydrophobic tails, and the glycocalyx for recognition and protection. The lecture also covers key cell junctions such as tight junctions (claudins and occludins), desmosomes (cadherins), hemidesmosomes (integrins), and gap junctions (connexins), plus major organelles including the nucleus, rough and smooth ER, Golgi apparatus, lysosomes, and mitochondria. It concludes by connecting defects in structures like lysosomes, cilia, and mitochondria to clinical outcomes and reinforces learning with brief check questions about ribosome assembly and cell functions."}
