Bacteria have incipient nucleus (nucleoid ) and hence they are placed in

Options

A. Prokaryota
B. Eukaryota
C. Fungi
D. Protista.

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Bacteria**: Bacteria are unicellular organisms that lack a well-defined nucleus. Instead of having a membrane-bound nucleus, they possess a region in the cytoplasm where their genetic material is located. This region is referred to as the nucleoid.

2. **Defining Nucleoid**: The nucleoid is an irregularly shaped area within the bacterial cell that contains the cell's genetic material (DNA). Unlike eukaryotic cells, which have a clearly defined nucleus surrounded by a nuclear membrane, bacteria do not have this structure.

3. **Classification of Organisms**: Organisms are classified into different categories based on their cellular structure. The two main categories are prokaryotes and eukaryotes. Prokaryotes are organisms that do not have a membrane-bound nucleus, while eukaryotes do.

4. **Identifying Prokaryotes**: Since bacteria do not have a well-defined nucleus and their genetic material is located in the nucleoid, they fall under the category of prokaryotes. Other organisms like fungi, protists, and plants are classified as eukaryotes because they possess a membrane-bound nucleus.

5. **Conclusion**: Therefore, due to the presence of an incipient nucleus (nucleoid) and the absence of a well-defined nucleus, bacteria are classified as prokaryotes.

**Final Answer**: Bacteria are placed in the category of **Prokaryota**.
