The movement of water molecules from a region of higher water potential to a region of lower water potential through a semi-permeable membrane is referred to:
Correct answer: B. Osmosis
- A. Active transport
- B. Osmosis
- C. Diffusion
- D. Photosynthesis
Explanation
Osmosis, the correct answer, refers to the movement of water molecules from an area of higher water potential to an area of lower water potential through a semipermeable membrane. This process occurs naturally and does not require energy. Option A, Active transport, is incorrect because it involves energy use to move substances against their gradient. Option C, Diffusion, does not specifically pertain to water and does not require a semipermeable membrane. Option D, Photosynthesis, is unrelated to the transport of water molecules.

About Forms and Functions of Plants
Plant nutrition and transport cover mineral uptake, photosynthesis, xylem movement of water and minerals, and phloem translocation of sugars. Plant growth regulators include auxins, gibberellins, cytokinins, abscisic acid and ethene, whose effects on cell division, elongation, dormancy, fruit ripening and tropic responses should not be confused with mineral nutrition.
