Amoeba is eukaryotic because it possesses

Options

A. Plasmid
B. Nucleus
C. Plasmalemma
D. DNA.

Answer

To answer the question "Amoeba is eukaryotic because it possesses," we need to analyze the options provided and understand the characteristics that define eukaryotic cells.

### Step-by-Step Solution:

1. **Understanding Eukaryotic Cells**:
- Eukaryotic cells are defined by the presence of a true nucleus. This means they have a distinct nuclear membrane that encloses the genetic material.
- In contrast, prokaryotic cells (like bacteria) do not have a true nucleus; their genetic material is not separated from the cytoplasm.

2. **Analyzing the Options**:
- **Option 1: Plasmid**:
- Plasmids are small, circular DNA molecules found in bacteria. They are not a characteristic of eukaryotic cells. Therefore, this option is incorrect.
- **Option 2: Nucleus**:
- The presence of a nucleus is a defining feature of eukaryotic cells. Since amoeba has a true nucleus, this option is likely correct.
- **Option 3: Plasma Lemma**:
- The plasma lemma (or plasma membrane) is present in both eukaryotic and prokaryotic cells. Thus, this option does not specifically indicate that amoeba is eukaryotic.
- **Option 4: DNA**:
- While eukaryotic cells have DNA, prokaryotic cells also contain DNA. The mere presence of DNA does not differentiate eukaryotes from prokaryotes.

3. **Conclusion**:
- The correct answer is **nucleus**. Amoeba is classified as a eukaryotic organism because it possesses a true nucleus, which is a key characteristic that distinguishes eukaryotes from prokaryotes.

### Final Answer:
Amoeba is eukaryotic because it possesses a nucleus.
