The light harvesting complex (LHC) is made up of -

Options

A. one molecule of Chl a
B. very few molecules of Chl a
C. hundreds of pigment molecules bound to proteins
D. Chl a + Chl c + protein + DNA

Answer

**Step-by-Step Solution:**

1. **Understanding the Light Harvesting Complex (LHC)**: The Light Harvesting Complex is a crucial component of the photosynthetic apparatus in plants. It plays a significant role in capturing light energy during the light reactions of photosynthesis.

2. **Identifying the Components of LHC**: The LHC is primarily composed of pigment molecules and proteins. These pigments are responsible for absorbing light energy, which is then used to drive the photosynthetic process.

3. **Evaluating the Options**:
- **Option 1**: Molecule of Chlorophyll-A - This is incorrect as LHC consists of more than just one type of chlorophyll.
- **Option 2**: Very few molecules of Chlorophyll-A - This is also incorrect; LHC contains a larger number of pigment molecules.
- **Option 3**: 100 of pigment molecules bound to protein - This option is accurate as it reflects the composition of LHC.
- **Option 4**: Chlorophyll-A plus Chlorophyll-C plus Protein plus DNA - This is incorrect; while chlorophyll and proteins are involved, DNA is not a component of LHC.

4. **Conclusion**: After evaluating the options, it is clear that the correct answer is **Option 3**: "100 of pigment molecules bound to protein."

5. **Final Answer**: The Light Harvesting Complex (LHC) is made up of hundreds of pigment molecules bound to proteins.
