Investigating Water Potential (AQA A-Level Biology): Flashcards

Ability of water molecules to move from one location to another

From high water potential to low water potential

Determine unknown concentrations by comparing with known standards

Point where water potential inside cells equals external solution (no net water movement)

0.0, 0.2, 0.4, 0.6, 0.8, 1.0

Where line crosses x-axis at zero change in mass

Increased mass (water moves into potato)

Decreased mass (water moves out of potato)
