What is the overall purpose of photosynthesis in plants and other photosynthetic organisms?

• A. To break down glucose to produce ATP for cellular work, releasing carbon dioxide and water
• B. To convert oxygen and glucose into carbon dioxide and water to generate energy for the cell
• C. To absorb nutrients from the soil and convert them directly into ATP without using light
• D. To convert light energy into chemical energy stored in sugars (such as glucose) while releasing oxygen as a byproduct

Answer: (D)

Verified step by step guidance

1. Understand that photosynthesis is a process used by plants and other photosynthetic organisms to capture energy from sunlight.
2. Recognize that the main goal of photosynthesis is to convert light energy into chemical energy, which is stored in the bonds of sugar molecules like glucose.
3. Know that during photosynthesis, carbon dioxide and water are used as raw materials to produce glucose and oxygen.
4. Remember that oxygen is released as a byproduct of photosynthesis, which is important for maintaining atmospheric oxygen levels.
5. Summarize that the overall purpose of photosynthesis is to create chemical energy in the form of sugars from light energy, supporting the organism's growth and energy needs.
