Question

unit 1 cumulative test (characteristics of life, biomolecules, cell structure and transport) 4 of 42 possible points: 2.13 the internal solute concentration of a plant cell is about 0.8 %. to demonstrate plasmolysis, it would be necessary to suspend the cell in what solution? ∘ 0.8% ∘ 0.4% ∘ 1.0 % ∘ distilled water

Explanation:

Plasmolysis occurs when a plant cell is placed in a hypertonic solution (solution with higher solute concentration than the cell's internal concentration), causing water to leave the cell. The plant cell's internal solute concentration is 0.8%. A 1.0% solution has a higher solute concentration, so it's hypertonic. A 0.8% solution is isotonic (no net water movement), 0.4% and distilled water are hypotonic (water enters the cell, causing turgor or swelling, not plasmolysis).

Answer:

C. 1.0 % (assuming the options are labeled as A. 0.8%, B. 0.4%, C. 1.0%, D. distilled water)
