Quiz: Osmosis and Diffusion

Movement of molecules from an area of high concentration to an area of low concentration.

• Diffusion

• Osmosis

• Endocytosis

• Exocytosis

One solution has a lower concentration of solute than another. 

• 1. Isotonic Solution

• Hypertonic Solution

• Hypotonic Solution

• Solid Solution

one solution has a higher concentration of solute than

another.

• 1. Apple

• 1. Banana

• Cat

• 1. Hypertonic Solution

 Movement of larger particles and ions across the cell membrane aided by protein channels/ transport proteins.

• Osmosis

• Diffusion

• 1. Active transport

• 1. Facilitated diffusion

These are called water channels

• 1. Ion channels

• Aquaporins

• 1. Ligand-gated channels

• 1. Potassium channel

Movement of molecules against the concentration gradient.

• 1. Osmosis

• Diffusion

• 1. Active transport

• 1. Passive transport

Cell swells and bursts open in a hypotonic solution.

• 1. Plasmolysis

• Cytolysis

• Dynamic equilibrium

• 1. Diffusion

 An energy-carrying molecule used in active transport 

• DNA 

  
  

• NADH 

  
  

•  ATP 

  
  

•  RNA

It is a type of active transport that takes bulky material into a cell. 

• Facilitated diffusion

• Endocytosis

• 1. Exocytosis

• Isotonic solution

 It is a type of passive transport where the diffusion of water through a selectively permeable membrane occurs.
