Which of the following physiological phenomenon is responsible of guttation :
Correct answer: B. Root pressure
- A. Capillary rise of water
- B. Root pressure
- C. Tensile strength
- D. All of these
Explanation
Guttation is the process by which plants excrete excess water in the form of droplets through specialized structures called hydathodes. It typically occurs during the night or early morning when the soil moisture is high and the transpiration rate is low.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
