Sunken stomata are present in:
Correct answer: B. Xerophytes
- A. Hydrophytes
- B. Xerophytes
- C. Mesophytes
- D. All of the above
Explanation
Sunken stomata are a characteristic adaptation found in xerophytes, which are plants adapted to dry, arid environments. This adaptation helps reduce water loss by protecting the stomata from direct exposure to the air, thereby minimizing transpiration. Hydrophytes, on the other hand, have adaptations suitable for water-rich environments and do not need to conserve water in the same way. Mesophytes live in environments with moderate water supply and do not have sunken stomata. Therefore, the correct answer is xerophytes.

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.
