Except cell membranes, cells of which of the following kingdom do not possess cell wall:

Options

A. Plantae
B. Monera
C. Fungi
D. Animalia

Explanation

To answer the question "Except cell membranes, cells of which of the following kingdoms do not possess cell walls?", we need to analyze the characteristics of the cell walls in different biological kingdoms.

### Step-by-Step Solution:

1. **Identify the Kingdoms**: The main kingdoms to consider are Plantae, Monera, Fungi, and Animalia.

2. **Analyze Plantae**:
- The Plantae kingdom includes all plants.
- Plant cells have a cell wall made primarily of cellulose, pectin, and sometimes hemicellulose.
- **Conclusion**: Plantae has a cell wall.

3. **Analyze Monera**:
- The Monera kingdom consists of prokaryotic organisms, primarily bacteria.
- Bacterial cells have a cell wall composed of peptidoglycan, which is a complex of sugars and amino acids.
- **Conclusion**: Monera has a cell wall.

4. **Analyze Fungi**:
- The Fungi kingdom includes organisms like mushrooms, yeast, and molds.
- Fungal cells have a cell wall made of chitin, which is a tough polysaccharide.
- **Conclusion**: Fungi has a cell wall.

5. **Analyze Animalia**:
- The Animalia kingdom consists of all animals.
- Animal cells do not have a cell wall; they only have a cell membrane.
- **Conclusion**: Animalia does not have a cell wall.

6. **Final Answer**: Based on the analysis, the kingdom whose cells do not possess a cell wall (except for the cell membrane) is **Animalia**.
