Difficulty: EasyPlant Biology and Photosynthesis

Which plant cell organelle absorbs sunlight and converts carbon dioxide and water into glucose?

  1. A
    Mitochondrion
  2. ChloroplastAnswer
  3. C
    Ribosome
  4. D
    Central vacuole

Answer

Chloroplast
Chloroplasts are the specialized organelles in plant cells that contain the green pigment chlorophyll. They absorb sunlight to drive photosynthesis, synthesizing glucose from carbon dioxide (CO2CO_2) and water (H2OH_2O).

Step-by-Step Solution

1
Identify the primary biological process described in the question.
Using sunlight, carbon dioxide, and water to synthesize glucose describes photosynthesis.
Pinpointing the physiological process allows direct identification of the specialized organelle responsible.
2
Match the process of photosynthesis to its specific cellular organelle.
Chloroplasts contain chlorophyll pigments and the enzymatic machinery required for photosynthetic energy conversion.
Plant cells contain chloroplasts specifically adapted to convert solar energy into chemical energy.
