GCSE Biology Osmosis
Osmosis is the diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane.
Must understand the water potential concept for higher marks.
What is Osmosis?
"Osmosis is the diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane."
Which answer best completes the statement? The nucleus contains ____ and controls the cell
Why are cultures in school laboratories usually incubated at about 25°C rather than 37°C?
Which change would increase the rate of diffusion?
Which answer best completes the statement? The permanent vacuole is filled with ____
Osmosis in Action
A dilute solution has a high concentration of water; a concentrated solution has a low concentration.
Plant cells rely on osmosis to stay turgid and support the plant structure.
Always mention "partially permeable membrane" to secure full marks for the definition of osmosis.
