Contains a phosphate, sugar and nitrogen base

• nucleic acid
• lipid
• carbohydrate
• protein

Solutes move against the concentration gradient, therefore energy is needed. 

• Passive Transport
• Active Transport

The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell
• Certain things can enter while others cannot
• The cell manually sorts through all materials
• Only certain cells can interact with the cell.
