Periplast of Euglena Continuous With longitudinal plates With transverse plates Made of spiral plates is

Options

A. Continuous
B. With longitudinal plates
C. With transverse plates
D. Made of spiral plates.

Answer

To answer the question about the periplast of Euglena, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Periplast**: The periplast is a protective layer found in Euglena, which is a type of unicellular eukaryote. It is important to know what the periplast is and its function.

2. **Identifying the Composition**: The periplast is specifically known to be made up of proteinaceous material. In the case of Euglena, this layer is referred to as the "pellicle."

3. **Structure of the Pellicle**: The pellicle of Euglena is not just a simple layer; it consists of a series of plates. These plates are arranged in a specific manner that contributes to the flexibility and structure of the organism.

4. **Types of Plates**: The pellicle is made up of spiral thecal plates. These plates are arranged spirally and allow for movement and flexibility, which is crucial for the motility of Euglena.

5. **Conclusion**: Based on the information gathered, the correct description of the periplast of Euglena is that it is made of spiral plates.

### Final Answer:
The periplast of Euglena is made of spiral plates.
