In lichens, the algal component is known as (A)____ and the fungal component as (B)_____

Answer

To answer the question regarding lichens and their components, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Lichens**: Lichens are a symbiotic association between two different organisms: algae and fungi. This relationship is mutually beneficial.

2. **Identifying the Components**: In this symbiotic relationship:
- The **algal component** is responsible for photosynthesis and is autotrophic, meaning it can produce its own food.
- The **fungal component** is heterotrophic, meaning it cannot produce its own food and relies on other sources for nutrients.

3. **Naming the Algal Component**: The algal component in lichens is specifically referred to as the **phycobiont**. This term derives from "phyco," which relates to algae.

4. **Naming the Fungal Component**: The fungal component in lichens is known as the **mycobiont**. The prefix "myco" relates to fungi.

5. **Final Answer**: Therefore, in lichens:
- (A) the algal component is known as **phycobiont**.
- (B) the fungal component is known as **mycobiont**.

### Summary:
- (A) Phycobiont
- (B) Mycobiont
