Most common asexual structure produced in algae is

Options

A. Thick walled
B. Multicellular
C. Flagellated
D. Produced in chains

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the most common asexual structure produced in algae.

2. **Identifying Asexual Structures in Algae**: Algae reproduce asexually through various structures. The most notable among these are spores, particularly zoospores.

3. **Defining Zoospore**: A zoospore is a type of motile spore that is produced by certain algae. The term "zoo" refers to motility, and "spore" refers to the reproductive structure.

4. **Characteristics of Zoospores**:
- **Motility**: Zoospores are flagellated, meaning they have flagella that allow them to swim.
- **Unicellular**: Zoospores are typically unicellular, not multicellular.
- **Not Thick-Walled**: They do not have thick walls; instead, they are generally more flexible to aid in movement.

5. **Evaluating the Options**:
- **Option 1: Thick-walled**: Incorrect, as zoospores are not thick-walled.
- **Option 2: Multicellular**: Incorrect, as zoospores are unicellular.
- **Option 3: Flagellated**: Correct, as zoospores have flagella for motility.
- **Option 4: Produced in chains**: Incorrect, as zoospores do not typically form chains.

6. **Conclusion**: The most common asexual structure produced in algae is the **flagellated zoospore**.
