front 1 Does diffusion require energy? | back 1 No |
front 2 In diffusion how does molecules move? | back 2 From high concentration to low concentration |
front 3 What is chemical potential? | back 3 The free energy available to do work to move one mole of molecule. |
front 4 What is a semipermeable membrane? | back 4 It is for nonliving membranes because they cannot change their shapes to pass through. An example is dialysis. |
front 5 What is a selectively permeable membrane? | back 5 For living membranes because they can alter their shapes to pass through. An example is a cell membrane |
front 6 What are the factors that affect osmosis and diffusion? | back 6 Membrane permeability, molecular weight, concentration gradient, and temperature |
front 7 What happens when a strong acid and a strong base meets? | back 7 Neutral chalk (precipitate) |
front 8 What is a hypotonic solution? What happens in plant and animal cells? | back 8 There will be a net flow of water out of the cell, and the cell will lose volume. Plant- turgid (normal) Animal- Lysed (burst) |
front 9 What is a hypertonic solution? What happens in plant and animal cells? | back 9 There will be a net flow of water into the cell, and the cell will gain volume. Plant- shriveled (plasmolyzed) Animal- shriveled |
front 10 What is a isotonic solution? What happens in plant and animal cells? | back 10 There will be no net flow of water into or out of the cell, and the cell’s volume will remain stable. Plant- flaccid Animal- normal |
