A protein rich layer which makes the body of Euglenoids flexible is called

Options

A. Pellicle
B. Murein
C. Cellulose plate
D. Pseudopodia

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question is about a specific type of organism known as Euglenoids. These organisms belong to the kingdom Protista and are primarily found in freshwater environments.

2. **Understand the Structure**: Euglenoids do not have a traditional cell wall like many other organisms. Instead, they possess a unique structure that provides support and flexibility.

3. **Define the Protein-Rich Layer**: The layer that replaces the cell wall in Euglenoids is made of proteins and is crucial for their flexibility and movement. This layer is not a rigid structure but allows for flexibility.

4. **Name the Layer**: The protein-rich layer that makes the body of Euglenoids flexible is called the "Pelicle." This layer is composed of microtubules, which are proteinaceous structures that provide both support and flexibility.

5. **Conclusion**: Therefore, the correct answer to the question is "Pelicle."

**Final Answer**: The protein-rich layer which makes the body of Euglenoids flexible is called **Pelicle**.
