IB Biology HL D2.3.11 Hl Water Potential in Plant Tissue Topic Practice

a. (when cell is placed in a hypotonic solution) surrounding/outside (of the root hair cell) is more dilute / has higher water potential

OR

water will enter the root hair cell

OR

water moves from high water potential to low water potential;

b. (positive) pressure potential will increase / become more positive;

c. (negative) solute/osmotic potential will increase / become less negative;

d. water potential inside the cell will increase / become less negative;

e. $\Psi_{w}=\Psi_{s}+\Psi_{p}$;

f. when cell's water potential equals that of the solution, (net) water movement stops;

For e. allow word equation:

$\Psi_{w}=$ water potential

$\Psi_{s}=$ solute potential

$\Psi_{p}=$ pressure potential
