1% of the absorbed water is used by plants in its activities during:
Correct answer: C. Photosynthesis
- A. Metabolism
- B. Respiration
- C. Photosynthesis
- D. Vernalization
Explanation
The correct answer is Photosynthesis. During photosynthesis, plants use about 1% of the absorbed water to convert carbon dioxide and light into glucose and oxygen. This process is critical for plant growth and energy production. Other options, like metabolism and respiration, involve water, but they do not specifically use 1% of the absorbed water. Vernalization is unrelated to water usage as it pertains to the flowering process induced by cold exposure.

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.
