Both algal and fungal partners are benefited by the association. What will happen if algal and fungal partners are separated from each other?

A

Both will die

B

Both will survive and grow normally and independent from each other

C

D

Fungal component will survive while algal partner will die

The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Lichens**: Lichens are a symbiotic association between two organisms: algae and fungi. The algal component (phycobiont) is responsible for photosynthesis and provides food, while the fungal component (mycobiont) offers shelter and absorbs water and nutrients. 2. **Mutual Benefits**: In this relationship, both partners benefit. The algae get protection and a suitable environment to grow from the fungi, while the fungi receive carbohydrates and other organic compounds from the algae. 3. **Separation of Partners**: If the algal and fungal partners are separated, the mutual benefits they provide to each other will no longer be available. 4. **Consequences of Separation**: - The algae will lack the protection and moisture provided by the fungi, making it difficult for them to survive independently. - The fungi will not have access to the food produced by the algae through photosynthesis, leading to starvation. 5. **Conclusion**: Since both partners are dependent on each other for survival, if they are separated, both the algal and fungal components will die. 6. **Correct Answer**: Therefore, the correct answer to the question is **Option A: Both will die**.
