Options

A. (a) Chl a
B. (b) Chl b
C. (c) chl c
D. (d) chl d

Answer

To solve the question "Which chlorophyll does not possess phytol?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Phytol**:
- Phytol is an acyclic diterpene alcohol that is a component of chlorophyll. It plays a crucial role in the structure of chlorophyll molecules.

2. **Identifying Chlorophyll Types**:
- There are several types of chlorophyll, including chlorophyll a, b, c, d, and f. Each type has a slightly different structure due to variations in their side chains (R1, R2, R3, R4).

3. **Analyzing Chlorophyll Structures**:
- Chlorophyll a and b contain phytol in their structure.
- Chlorophyll d and f also have phytol as part of their structure.
- However, chlorophyll c is known to lack the phytol tail.

4. **Conclusion**:
- Since chlorophyll c does not possess phytol, the answer to the question is chlorophyll c.

5. **Final Answer**:
- Therefore, the correct answer is **chlorophyll c**.
