E. histolytica does not show

Options

A. Binary fission
B. Encystation
C. Budding
D. Excystation.

Answer

To solve the question regarding Entamoeba histolytica and what it does not show, we will analyze the options provided and determine which one is incorrect based on the characteristics of this organism.

### Step-by-Step Solution:

1. **Understanding Entamoeba histolytica**:
- Entamoeba histolytica is a unicellular eukaryotic organism and a human intestinal parasite known for causing dysentery. It primarily infects the large intestine.

2. **Analyzing the Options**:
- The options given are:
- A) Binary fission
- B) Encystation
- C) Budding
- D) Excystation

3. **Evaluating Each Option**:
- **A) Binary fission**:
- Entamoeba histolytica reproduces by binary fission, which involves the equal division of the cell into two daughter cells. This is a true statement.

- **B) Encystation**:
- Encystation is the process where the organism forms a cyst to survive in harsh conditions. Entamoeba histolytica can undergo this process, making this statement true.

- **C) Budding**:
- Budding is a form of asexual reproduction where a new organism develops from an outgrowth of the parent. This process is not exhibited by Entamoeba histolytica, making this statement false.

- **D) Excystation**:
- Excystation is the process where a cyst breaks open to release the active trophozoite. This is a part of the life cycle of Entamoeba histolytica, thus this statement is true.

4. **Conclusion**:
- Since Entamoeba histolytica does not show budding, the correct answer to the question is option C) Budding.

### Final Answer:
Entamoeba histolytica does not show **budding**.
