Question

How do our results support what we know about photosynthesis?

a. The number of bubbles represents the amount of oxygen produced by photosynthesis, so the more light available in the reaction, the more O₂ is produced. b. The number of bubbles represents the amount of CO₂ produced by photosynthesis, so the more bubbles made, the more photosynthesis
c. The number of bubbles represents the amount of oxygen produced, so as we decrease the light levels, the plant makes more O₂.

Answer 1

Our results support what we know about photosynthesis by showing that more light available in the reaction leads to more oxygen produced, the number of bubbles generated does not represent the amount of carbon dioxide produced, and as light levels decrease, the plant makes more oxygen.

Step-by-step explanation:

Photosynthesis is the process by which plants convert carbon dioxide and water into glucose and oxygen, using sunlight as the source of energy. Our results support what we know about photosynthesis in several ways:

1. The number of bubbles generated in the reaction represents the amount of oxygen produced by photosynthesis. This means that when there is more light available, more oxygen is produced because the plants have more energy to carry out the reaction. (Answer A)
2. The number of bubbles does not represent the amount of carbon dioxide produced by photosynthesis. In fact, carbon dioxide is consumed during photosynthesis, not produced. So, the more bubbles made, the more photosynthesis is occurring, but not directly related to the amount of CO₂ produced. (Answer B)
3. As we decrease the light levels, the plant makes more oxygen because there is less energy available for photosynthesis. This means that the plant compensates by producing more oxygen to make up for the lower energy levels. (Answer C)
