Carbohydrates are energy-containing compounds produced by photosynthesis; which term describes these compounds?

• A. Carbohydrate
• B. Fertilizer
• C. Degree Days
• D. Climate

Answer: (A)

Carbohydrates are energy-rich molecules that plants make during photosynthesis. The plant uses light energy to convert carbon dioxide and water into sugars and starches, which store chemical energy for growth, metabolism, and stress tolerance. The term that describes these energy-containing compounds is carbohydrate. This differs from fertilizer, which supplies nutrients to the plant; degree days, which measure accumulated warmth to predict development; and climate, which refers to long-term weather patterns. In turf management, carbohydrates produced by photosynthesis are essential energy reserves that support healthy growth and resilience.
