Cell Movement and Transport DVD

15 minutes

Cell Movement and Transport is organized into short-play learning modules, for concise instruction.

1. Structure and Behaviour of the Plasma Membrane (00:57) Phospholipid bi-layers behave as a two dimensional fluid surrounding the cell.
2. Osmosis (2:25) Differences in water-potential between the cell interior and its surroundings affect the net movement of water into and out of a cell.
3. Transport Proteins (00:54) Biological membranes swarm with proteins that act as gates and channels, allowing substances to enter and leave cells.
4. Phagocytosis (1:39) Many types of free-living cells engulf food for digestion within food vacuoles.
5. Pinocytosis (00:25) Cells bring in nutrient fluids by incorporating them into small vesicles.
6. Receptor Mediated Endocytosis (00:47) Receptor proteins on the cell surface trap specific types of molecules that are taken in by endocytosis.
7. Golgi Function (00:38) The Golgi apparatus is a folded stack of membranes that sorts and packages cell products.
8. Lysosomes and Hydrolytic Digestion (1:20) Demonstrates the action of lysosomes and organelles that hold and transport hydrolytic enzymes.
9. Microtubules (1:04) Quickly assembling and breaking down, microtubules create support structures and function in many kinds of cell movement.
10. Cilia (1:10) An amazing molecular hook and claw action drives the ciliary beat.
11. Actin and Myosin Motor Proteins (1:15) The interaction between these two proteins moves cell particles and produces the contraction of muscles.
