Pigment combination of a carotenoid is:
Correct answer: C. Yellow, orange, red, or brown
- A. Blue, green, brown, or red
- B. Orange, yellow, blue, or brown
- C. Yellow, orange, red, or brown
- D. Blue, red, orange, or brown
Explanation
Carotenoids are accessory pigments found in plants that include colors such as yellow, orange, red, and brown. They are crucial in photosynthesis because they absorb light energy and protect chlorophyll from photo-damage. The other options are incorrect as they include colors like blue and green, which are typically associated with chlorophyll pigments, not carotenoids.

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.
