Cell transport Flashcards
Movement of molecules from high to low concentration.
Diffusion
Movement of molecules which doesn’t require energy.
Passive transport
Movement of water molecules from high to low water concentration through a selectively permeable membrane
Osmosis
State of a plant cell after water has entered by osmosis.
Turgid
State of a plant cell after water has left by osmosis (cytoplasm shrunk away from cell wall).
Plasmolysed
Change in vacuole in a turgid cell.

What word is used to describe these cells?
Flaccid
What word is used to describe these cells?
Turgid
Type of transport where energy is required for membrane proteins to move molecules up a concentration gradient (low to high concentration).
Active transport
Plasmolysed
State of a plant cell after water has left by osmosis (cytoplasm shrunk away from cell wall).
