Osmosis & Diffusion
Question | Answer |
---|---|
The movement of water specific molecules from an area of higher concentration to lower concentration. | Osmosis |
The cell membrane selecting certain molecules to allow them in and out of the cell. | Selectively Permeable |
The movement of molecules (Oxygen, Calcium, Glucose etc.) into and out of the cell. | Diffusion |
The movement of molecules that does NOT require energy. | Passive Transport |
The movement of molecules that DOES require energy. | Active Transport |
What are a few example(s) of Passive Transport | -Osmosis -Diffusion |
In which direction to molecules ALWAYS like to move? | Higher Concentration to Lower Concentration |
Think of some examples of Diffusion in every day life. | Answers will vary |
What happens to the cell if the water molecules are more highly concentrated inside the cell rather than outside? | The cell could swell and burst |
What happens to the cell if the water molecules are more highly concentrated outside of the cell rather than inside? | The cell could shrink/shrivel |
