Question

homework - reactions of photosynthesis
the image shows a biological process that occurs in plants.
image of tree with sun, carbon dioxide, glucose, water (h₂o), oxygen
what can be concluded from the image?
○ plants convert solar energy into chemical energy by respiration.
○ plants convert chemical energy into solar energy by respiration.
○ plants convert solar energy into chemical energy by photosynthesis.
○ plants convert chemical energy into solar energy by photosynthesis

Explanation:

1. Analyze the process: The image shows the sun (solar energy), water, carbon dioxide as inputs, and glucose (chemical energy) and oxygen as outputs, which is photosynthesis.
2. Evaluate each option:

• Option 1: Respiration is for energy release, not energy conversion from solar to chemical. Eliminate.
• Option 2: Respiration doesn't convert chemical to solar energy, and the process here is not respiration. Eliminate.
• Option 3: Photosynthesis uses solar energy to convert CO₂ and H₂O into glucose (chemical energy), matching the image. Correct.
• Option 4: Photosynthesis doesn't convert chemical to solar energy; it's the reverse. Eliminate.

Answer:

C. Plants convert solar energy into chemical energy by photosynthesis.
