Question

8. The distilled water is A) isotonic B) hypertonic. C) hypotonic. D) toxic solution to plant cell. True or False (1pt/each question) The Na concentration in extracellular fluid is 3M, the Na concentration in cytosol is 0.15 M. Na" will diffuse into the cell though Na channel. Bulk transportation including exocytosis and endocytosis consumes energy. credit. Choose one correct answer (2pts) Extra Water can go across cell membrane by A) simple diffusion and active transport mosis and facilitated diffusion facilitated diffusion and active transport D) Aquaporin and exocytosis

Explanation / Answer

8. Distilled water is made up the vaporization of water hence it does not contain any salt. Whereas intracellular environment contain trace amount of salt and other ions, therefore, distilled water is hypotonic for the plant cells.

False . In this condition water will come out of the cell and cell will not Na+ inside the cell

True . Bulk transport endocytosis and exocytosis required ATP.

In extra credit your answer is right.
