The correct Answer is:
To determine the ratio of chlorophyll A to chlorophyll B in shade plants, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Role of Chlorophyll**: - Chlorophyll A is the primary photosynthetic pigment, while chlorophyll B acts as an accessory pigment that helps in capturing light energy and transferring it to chlorophyll A. 2. **Identify the Environment**: - Shade plants are adapted to grow in low light conditions. This affects the chlorophyll composition in these plants. 3. **Know the Typical Ratio**: - In general, the ratio of chlorophyll A to chlorophyll B in most plants is approximately 3:1. 4. **Adjust for Shade Plants**: - In shade plants, this ratio changes due to their adaptation to lower light levels. Research indicates that the ratio of chlorophyll A to chlorophyll B in shade plants is approximately 1.4:1. 5. **Select the Correct Option**: - From the given options (4.1:1, 1.4:1, 0.7:1, 5.5:1), the correct answer is 1.4:1. ### Final Answer: The ratio of chlorophyll A to chlorophyll B in shade plants is **1.4:1**. ---
