Paul Andersen gives you a brief introduction to the cell membrane. He starts by describing amphipathic nature of a phospholipid and how it assembles into a membrane. He gives an overview of the fluid mosaic model inside cells. He also discusses the movement of material across a membrane and the role of proteins in movement and function.
Cell membranes are semipermeable, meaning they have control over what molecules can or cannot pass through. Some molecules can just drift in and out, others require special structures to get in and out of a cell, while some molecules even need an energy boost to get across a cell membrane.

The water cycle is the continuous movement of water in and around the Earth. As previously mentioned, water never really goes away -- it just changes form. The sun drives the entire water cycle and is responsible for its two major components: condensation and evaporation. When the sun heats the surface of water, it evaporates and ends up in the ...
MAIN IDEA: Endocytosis and exocytosis transport materials across the membrane in vesicles. 7. A cell may transporta substance in too large to cross the membrane. if the substance is 8. Dunng endocytosis, the vesicle membrane fuses with a lysosome, and the membrane and its contents are broken down by S
Concept 7.2 Membrane structure results in selective permeability. A steady traffic of small molecules and ions moves across the plasma membrane in both directions. Movement of a molecule through a membrane depends on the interaction of the molecule with the hydrophobic core of the membrane.
