Difficulty: EasyPlant Biology and Photosynthesis

Photosynthesis converts radiant solar energy into chemical energy stored within organic molecules. Which carbohydrate is the primary simple sugar produced by plants during this process?

  1. A
    Glycogen
  2. B
    Carbon dioxide
  3. GlucoseAnswer
  4. D
    Lactic acid

Answer

Glucose is the primary simple sugar synthesized by plants during photosynthesis.
Glucose is the primary monosaccharide produced during photosynthesis. Plant cells combine carbon dioxide and water in the presence of sunlight to synthesize glucose (C6H12O6C_6H_{12}O_6), which provides immediate cellular energy and serves as the fundamental building block for complex plant carbohydrates.

Step-by-Step Solution

1
Identify the basic chemical reaction of photosynthesis
During photosynthesis, plant chloroplasts use light energy to convert carbon dioxide (CO2CO_2) and water (H2OH_2O) into glucose (C6H12O6C_6H_{12}O_6) and oxygen (O2O_2).
Recognizing the chemical equation identifies the organic sugar formed as an end product.
2
Evaluate the products to identify the simple carbohydrate
Glucose is a six-carbon simple sugar (monosaccharide) that stores the captured chemical energy.
Differentiates the primary photosynthetic sugar from animal storage polymers and respiratory byproducts.
