What are the 2 parts of a phospholipid? 

• Hydrophobic head, hydrophilic tails 
• Hydrophobic heads, hydrophobic tails 
• Hydrophilic heads, hydrophobic tails 
• Hydrophilic heads, hydrophilic tails 

What is an isotonic solution?

• When solutions are in equilibrium 
• When the solution has more solute 
• When the solution has less solute 
• Has a greater pressure 

What is the function of Microfilaments?

• Energy factories to provide power to the cell
• Modifies and packages proteins and lipids
• Move towards cell ends for division
• Reinforces cell shape

Cholesterol are found in the plasma membrane. Suggest its function:

• facilitate movement of larger molecules such as fatty acids and amino acids
• Maintain flexibility of the phospholipids bilayer
• Regulate movement of substances in and out of the cell
• Involve active transport such as sodium and potassium pump
