Cellular Structure & Transport

In this session, we are talking about cell structure and cell transport. We begin by talking about the most important cell structures (mitochondria, nucleus, endoplasmic reticulum). We cover the plasma membrane (Golgi apparatus, Lysosome, Chloroplast). We discuss cell structure (vacuole, ribosome, vesicle diagram) and also use a graphic to explain prokaryotes versus eukaryotes, and then we move on to what can and can’t get through the phospholipid bilayer (selectively permeable). We cover the concentration gradient diagram because we need to know how substances are going to move. We cover the types of movement (diffusion, subsets of diffusion, passive transport, osmosis, facilitated diffusion, and active transport). We use a chart to show what gets through and how they do it (types of transport, energy required, molecules transported, concentration gradient). We show how water moves. Finally, we end with cell environments (hypertonic, isotonic, hypotonic, plasmolyzed, flaccid and turgid).
