Organism having pellicle which makes their body flexible are also characterised by the presence of all except :-

Options

A. Pigments are identical to those present in higher plants
B. Behave like heterotrophs by predating on other smaller organism when deprived of sunlight
C. Having silicicated and indestructible cell wall
D. Heterokont (two types of flagella) type of flagellation in which one is short and other is long

Answer

To solve the question regarding organisms that have a pellicle making their body flexible, we will analyze the characteristics of such organisms, particularly focusing on Euglena, which is a well-known example.

### Step-by-Step Solution:

1. **Identify the Organism**: The organism in question is Euglena, which is known for having a pellicle that provides flexibility to its body.

2. **Characteristics of Euglena**:
- **Pellicle**: Euglena has a pellicle, which is a flexible outer covering that allows it to change shape.
- **Autotrophic and Heterotrophic**: Euglena is primarily autotrophic due to the presence of chlorophyll, allowing it to perform photosynthesis. However, it can also act as a heterotroph when sunlight is not available by preying on smaller organisms.
- **Flagella**: Euglena possesses two flagella, one long and one short, which aid in movement.

3. **Analyze the Options**: The question asks for the characteristic that is NOT present in Euglena. The options typically include:
- Presence of pigments identical to those in higher plants (correct, as Euglena contains chlorophyll).
- Ability to act as a heterotroph when deprived of sunlight (correct).
- Presence of a silicated and indestructible cell wall (incorrect, as Euglena does not have a traditional cell wall; it has a pellicle instead).

4. **Conclusion**: The characteristic that is NOT present in Euglena is the presence of a silicated and indestructible cell wall. Therefore, the correct answer is the option that states this characteristic.

### Final Answer:
The organism having a pellicle which makes their body flexible is characterized by the presence of all except **a silicated and indestructible cell wall**.
