Moneran that reproduce by binary fission is

Options

A. Euglena
B. E.coil
C. Yeast
D. Both 1 and 2

Answer

To solve the question "Moneran that reproduces by binary fission is," we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification of Organisms**:
- Organisms are classified into five kingdoms: Monera, Protista, Plantae, Fungi, and Animalia.
- Monera includes prokaryotic organisms, which lack a true nucleus.

2. **Identify the Characteristics of Monera**:
- Monera consists of unicellular organisms.
- They reproduce asexually, primarily through binary fission.

3. **Review the Given Options**:
- The options provided are:
1. Euglena
2. E. coli
3. Yeast
4. 1 and 2 (referring to Euglena and E. coli)

4. **Analyze Each Option**:
- **Option 1: Euglena** - This is a protist, not a Monera. It reproduces by binary fission but does not belong to the Monera kingdom.
- **Option 2: E. coli** - This is a bacterium that belongs to the Monera kingdom and reproduces by binary fission. This option is correct.
- **Option 3: Yeast** - Yeast is a fungus and reproduces by budding, not binary fission. Therefore, this option is incorrect.
- **Option 4: 1 and 2** - Since Euglena is not a Monera, this option is also incorrect.

5. **Conclusion**:
- The only organism from the options that is a Monera and reproduces by binary fission is **E. coli**.

### Final Answer:
The Moneran that reproduces by binary fission is **E. coli**.
