1. 12.14.17 Identify the type of cell transport
I can describe and draw the four parts of the cell membrane.

2. The Cell Membrane
A fluid mosaic model that provides support and protection for the cell.

3. Phospholipids
Phospholipids have a hydrophilic head (glycerol) and two hydrophobic tails (fatty acids).
Function -- majority of the membrane, allows for diffusion through the membrane

4. Cholesterol Cholesterol molecules are a waxy chain of fat.
Function -- these keep the membrane stable (not too fluid, not too stiff)

5. Proteins
Made of chains of amino acids folded together to make a specific shape.
Function -- transport substances, receive messages, recognize cells, connect cells…

6. Carbohydrates Carbohydrates are made up of chains of sugar molecules.
Function — cell recognition.

7. Where does transport happen?
