The proteinaceous layer called pellicle and two flagella one long and one short are seen in organisms which are

Options

A. unicellular , prokaryotic and are photosynthetic as well as heterotrophic
B. unicellular , prokarytic and are heterotrophic
C. unicellular , eukaryotic and are photosynthetic as well as heterotrophic
D. unicellular , eukaryotic and are heterotrophic

Answer

To solve the question regarding the organism that has a proteinaceous layer called pellicle and two flagella (one long and one short), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Characteristics**:
- The organism has a proteinaceous layer called pellicle.
- It possesses two flagella, one long and one short.
- We need to determine if it is unicellular, prokaryotic or eukaryotic, and whether it is photosynthetic or heterotrophic.

2. **Analyze the Options**:
- **Option 1**: Unicellular prokaryotic and photosynthetic as well as heterotrophic.
- **Option 2**: Unicellular prokaryotic and heterotrophic.
- **Option 3**: Unicellular eukaryotic and photosynthetic as well as heterotrophic.
- **Option 4**: Unicellular eukaryotic and heterotrophic.

3. **Recall the Organism**:
- The characteristics described (pellicle and two flagella) are typical of the organism **Euglena**.
- Euglena is a unicellular eukaryotic organism that has chloroplasts, allowing it to be photosynthetic, but it can also absorb nutrients from its environment, making it heterotrophic.

4. **Confirm the Classification**:
- **Euglena** is classified as a eukaryotic organism because it has a defined nucleus and organelles.
- It is unicellular and can perform photosynthesis due to the presence of chloroplasts, while also being capable of heterotrophy.

5. **Select the Correct Option**:
- Based on the analysis, the correct answer is **Option 3**: Unicellular eukaryotic and photosynthetic as well as heterotrophic.

### Final Answer:
The organism which has a proteinaceous layer called pellicle and two flagella (one long and one short) is **Euglena**, which is classified as **Option 3: Unicellular eukaryotic and photosynthetic as well as heterotrophic**.
