Pellicle in Euglena is made up of

Options

A. Carbohydrates
B. Proteins
C. Lipids
D. All

Answer

**Step-by-Step Solution:**

1. **Understanding Euglena**: Begin by recognizing that Euglena is a type of organism classified under the eukaryotes. They are known for their unique features, including the presence of flagella.

2. **Identifying the Pellicle**: The pellicle is a layer that surrounds the Euglena cell. It is crucial to understand its composition to answer the question correctly.

3. **Composition of the Pellicle**: The pellicle in Euglena is primarily made up of proteins. It is important to note that this layer is not just any protein but a specialized type of protein.

4. **Structure of the Pellicle**: The pellicle is supported by a substructure of microtubules, which are arranged in a spiraling pattern around the cell. This structural arrangement contributes to the flexibility and shape of the Euglena.

5. **Eliminating Other Options**: The question provides multiple-choice options: carbohydrate, protein, lipids, or all. Since the pellicle is primarily made of specialized proteins and does not include carbohydrates or lipids in its composition, we can eliminate those options.

6. **Conclusion**: The correct answer to the question "Pellicle in Euglena is made up of" is **protein**.
