In earlier classification system which organisms were included under "Plants" :-

Options

A. Bacteria, BGA, Fungi, Bryophyte, Ferns and Spematophytes
B. Bacteria, protozoa, Green algae, Porifera and Moss
C. Green algae, Moss, Bryophytes, Protozoa and Porifera
D. Moss, Ferns, Gymnosperms, Protozoa and Porifera

Answer

### Step-by-Step Solution:

1. **Understanding the Earlier Classification System**:
- In earlier classification systems, organisms were categorized primarily based on the presence or absence of a cell wall. Organisms with a cell wall were generally classified under "Plants".

2. **Identifying Organisms with Cell Walls**:
- **Bacteria**: These organisms have a cell wall made of peptidoglycan. In the past, this characteristic led to their classification under plants.
- **Blue-Green Algae**: Also known as cyanobacteria, they possess a cell wall made of cellulose, which is a characteristic of plants.
- **Fungi**: They have a cell wall made of chitin. Historically, they were included in the plant kingdom due to the presence of a cell wall.
- **Bryophytes**: These are non-vascular plants that have a cell wall made of cellulose, placing them firmly in the plant category.
- **Angiosperms and Gymnosperms**: These are higher plants that also have cell walls made of cellulose.

3. **Excluding Organisms without Cell Walls**:
- **Protozoa**: These are unicellular organisms that do not have a cell wall, thus they were not classified under plants.
- **Porifera (Sponges)**: These organisms also lack a true cell wall, which excludes them from the plant category.

4. **Conclusion**:
- Based on the above analysis, the organisms that were included under "Plants" in the earlier classification system are bacteria, blue-green algae, fungi, bryophytes, and higher plants (angiosperms and gymnosperms). Protozoa and porifera are excluded due to the absence of a cell wall.

### Final Answer:
The organisms included under "Plants" in the earlier classification system are:
- Bacteria
- Blue-Green Algae
- Fungi
- Bryophytes
- Angiosperms and Gymnosperms
