Presentation transcript:

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

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

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

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

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

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

Where does transport happen?
