Chlorophyll can be extracted by

Options

A. water
B. organic solvent
C. Both (1) and (2)
D. none of these

Answer

### Step-by-Step Solution:

1. **Understanding Chlorophyll**: Chlorophyll is a green pigment found in the chloroplasts of green plants. It plays a crucial role in photosynthesis by absorbing sunlight.

2. **Location of Chlorophyll**: This pigment is predominantly present in the leaves of green plants, where it facilitates the process of photosynthesis.

3. **Extraction Method**: To extract chlorophyll from plant leaves, organic solvents are used. These solvents can break down the lipid bonds that hold chlorophyll molecules.

4. **Common Organic Solvents**: Ethanol is a commonly used organic solvent for this purpose. Other solvents like methanol and propanol can also be used to extract chlorophyll.

5. **Ineffectiveness of Water**: Water does not extract chlorophyll. Even during rain, chlorophyll remains intact in the leaves, as it does not break down in the presence of water.

6. **Application in Experiments**: In laboratory settings, ethanol is often used to remove chlorophyll from green leaves during photosynthesis experiments to study the process without the interference of the pigment.

7. **Conclusion**: The correct answer to the question "Chlorophyll can be extracted by?" is organic solvents, specifically ethanol.
