BGA (blue green algae) are included in which of the following groups ?

Options

A. Bryophytes
B. Prokaryotes
C. Protista
D. Fungi

Answer

**Step-by-Step Solution:**

1. **Identify Blue-Green Algae**: Blue-green algae are commonly known as cyanobacteria. They are photosynthetic organisms that can be found in a variety of aquatic environments.

2. **Determine the Classification**: Cyanobacteria are classified as prokaryotic organisms. This means they do not have a true nucleus or membrane-bound organelles. Their genetic material is organized in a structure known as a genophore.

3. **Refer to Classification Systems**: According to the five-kingdom classification system proposed by Sir R. H. Whittaker, all prokaryotic organisms, including cyanobacteria, are placed under the kingdom Monera.

4. **Examine the Options**: The options provided in the question include:
- Bryophytes
- Prokaryotes
- Protista
- Mycota

- **Bryophytes**: This group belongs to the kingdom Plantae and consists of eukaryotic organisms, so this option is incorrect.
- **Prokaryotes**: This is the correct classification for blue-green algae, as they are prokaryotic organisms.
- **Protista**: This kingdom includes unicellular eukaryotic organisms, which does not include cyanobacteria, so this option is incorrect.
- **Mycota**: This kingdom includes fungi, which are multicellular eukaryotic organisms, making this option incorrect as well.

5. **Conclusion**: Based on the classification, blue-green algae (cyanobacteria) are included in the group of prokaryotes.

**Final Answer**: Blue-green algae (BGA) are included in the group of prokaryotes.
