Organisms without nucleus and cell organelles belong to
(i) fungi (ii) protista
(iii) cyanobacteria (iv) archaebacteria

Options

A. (i) and (ii)
B. (iii) and (iv)
C. (i) and (iv)
D. (ii) and (iii)

Explanation

To solve the question "Organisms without nucleus and cell organelles belong to," we will analyze the options provided:

1. **Understanding the Options**:
- (i) Fungi
- (ii) Protista
- (iii) Cyanobacteria
- (iv) Archaebacteria

2. **Identifying Characteristics**:
- **Fungi**: These are eukaryotic organisms, meaning they have a well-defined nucleus and cell organelles.
- **Protista**: This group also consists of eukaryotic organisms, which possess a well-developed nucleus and various cell organelles.
- **Cyanobacteria**: These are prokaryotic organisms, which means they lack a true nucleus and have a nucleoid instead. They also lack membrane-bound cell organelles.
- **Archaebacteria**: Similar to cyanobacteria, archaebacteria are also prokaryotic and do not have a well-defined nucleus or cell organelles.

3. **Conclusion**:
- Both cyanobacteria and archaebacteria are prokaryotes that do not have a true nucleus or cell organelles. Therefore, the organisms without a nucleus and cell organelles belong to either cyanobacteria or archaebacteria.

4. **Final Answer**:
- The correct answer is **(iii) cyanobacteria and (iv) archaebacteria**. Since the question asks for organisms without a nucleus and cell organelles, both options (iii) and (iv) are correct.
