In the context of photosynthesis, do plants require soil in order to carry out photosynthesis?

• A. Yes; soil provides carbon dioxide, so without soil plants cannot obtain CO2 for photosynthesis.
• B. No; photosynthesis requires light, carbon dioxide, water, and chlorophyll, but soil itself is not a direct requirement for the reaction.
• C. Yes; soil supplies light energy, so photosynthesis cannot occur without soil.
• D. Yes; soil is where chlorophyll is produced, so photosynthesis cannot occur without soil.

Answer: (B)

Verified step by step guidance

1. Understand the basic requirements for photosynthesis: light energy, carbon dioxide (CO\_2), water (H\_2O), and chlorophyll.
2. Recognize that soil is primarily a medium that provides water and minerals to plants, but it is not directly involved in the photosynthesis chemical reaction.
3. Recall that carbon dioxide is obtained from the air, not from the soil, and light energy comes from sunlight, not soil.
4. Know that chlorophyll is produced within the plant cells (specifically in chloroplasts) and does not depend on soil itself for its production.
5. Conclude that while soil supports plant growth by supplying water and nutrients, it is not a direct requirement for photosynthesis to occur.
