osmosis / diffusion
Question | Answer |
---|---|
what type of passive cell transport occurs through a semi-permiable membrane? | osmosis |
what type of passive cell transport occus through a permeable membrane? | diffusion |
isotonic | equal amount of water and salt |
hypotonic | more water, less salt (ruptured blood cell) |
hypertonic | less water, less salt (crenated blood cell) |
acidic ph solution? | <7 |
alkaline ph solution? | >7? |
Neutral ph solution? | 7 |
natural ph of blood? | 7.4 |
osmosis | water travels from a high concentration to a low concentration through a semi-permeable membrane |
diffusion | molecules or ions (solute) moving from a high concentration to an area of low concentration |
solute | what is being dissolved (eg salt, sugar) |
solvent | what is dissolving the solute (eg, water, vinegar) |
