What factors affect osmosis in plants?
Tonicity
Isotonic
Same Concentration of solutes
Hypertonic
Higher concentration Outside and lower inside
Hypotonic
Higher concentration inside and lower outside
Variations of Osmosis
Endosmosis
When a substance is placed in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid or undergoes deplasmolysis. This is known as endosmosis.
Exosmosis
When a substance is placed in a hypertonic solution, the solvent molecules move outside the cell and the cell becomes flaccid or undergoes plasmolysis. This is known as exosmosis.
Water Potential Gradient
Higher Gradient
Rate of osmosis increases
Potential difference
Distance of flow per unit
The lesser molecules are in Lower concentration
Higher concetration Molecules can enter
High Concentration to Low Concetration
direct effect on osmosis
Surface Area
Larger
More Space for the molecules to move
Smaller
movement
Slower
Restricted
Temperature
Increase
Increase osmotic Pressure
Aquaporins
increases Rate
Dilute solutions
More to Less
