Chlorophyll b constitutes about _______ of the total cholorphyll content.

Options

A. 0.25
B. 0.5
C. 0.75
D. 0.05

Answer

To solve the question regarding the proportion of chlorophyll b in the total chlorophyll content, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chlorophyll Types**: Recognize that there are different types of chlorophyll, including chlorophyll A and chlorophyll B. Chlorophyll A is the primary pigment involved in photosynthesis, while chlorophyll B acts as an accessory pigment.

2. **Function of Chlorophyll B**: Understand that chlorophyll B's role is to assist chlorophyll A by capturing light energy and transferring it to chlorophyll A, thereby enhancing the overall efficiency of photosynthesis.

3. **Proportional Relationship**: It is important to note that chlorophyll A is present in a greater amount compared to chlorophyll B. The ratio of chlorophyll A to chlorophyll B is approximately 3:1.

4. **Calculating the Percentage**: If we consider the total chlorophyll content as 100%, and given the ratio of chlorophyll A to chlorophyll B (3:1), we can deduce the following:
- Chlorophyll A constitutes 75% (3 parts out of 4 total parts).
- Chlorophyll B constitutes 25% (1 part out of 4 total parts).

5. **Final Answer**: Therefore, chlorophyll B constitutes about **25%** of the total chlorophyll content.

### Answer:
Chlorophyll b constitutes about **25%** of the total chlorophyll content.
