Plasma Membrane and Cell Wall

*Phospholipid

Phosphate Head- Hydrophilic LOVES WATER Lipid Tail- Hydrophobic HATES Water

Organisms and their cell wall structure

1.Plants 2.Bacteria 3.Fungus 4.Phytoplankton

*2 Types of proteins

1.Transport Protein: helps larger substances pass through bilayer 2.Glycoprotein- protein with carbohydrate - Helps cell recognize similar cells; similar cells form tissues

*Cholesterol

Location: Founds in between phospholipids in the bilayer Function: Keeps membrane together; phosphate heads are not attached together

*Cell Wall

Location: Location outside of cell membrane in some organisms Function: Provides structure and support

*Protein

Location: Within phospholipid bilayer

*Carbohydrate

Location: on top of protein phospholipids Function: Helps recognize similar cells to form tissues OR recognize foreign substances in cell

*Phospholipid Bilayer

membrane made up of 2 layers of Phospholipids Location: Surrounds the cells & organelles Function: Controls what comes in & out of the cell; gatekeeper
