Answer

**Step-by-Step Text Solution:**

1. **Understanding Lichens**: Lichens are a unique symbiotic association between two organisms: algae and fungi.

2. **Identifying the Partners**: In this partnership, one organism is responsible for photosynthesis, which is the process of converting light energy into chemical energy (food).

3. **Role of Algae**: The organism that contains chlorophyll and is capable of photosynthesis is the algae. Algae contain the green pigment chlorophyll, which is essential for capturing light energy.

4. **Role of Fungi**: The other partner, fungi, does not contain chlorophyll and cannot perform photosynthesis. Instead, fungi are heterotrophic, meaning they rely on other organisms for their nutrients.

5. **Conclusion**: Therefore, in lichens, the chlorophyll-containing partner is an **alga**.

**Final Answer**: In lichens, the chlorophyll-containing partner is an **alga**.
