The correct Answer is:
To determine where the siliconous cell wall is present, we can break down the options given: 1. **Understanding Siliconous Cell Walls**: Siliconous cell walls are primarily characterized by the presence of silica (SiO2). This is a key feature that distinguishes certain organisms. 2. **Evaluating the Options**: - **Blue-green algae**: Also known as cyanobacteria, these organisms do not have siliconous cell walls. Instead, they have peptidoglycan in their cell walls. - **Diatoms**: These are a group of unicellular photosynthetic organisms known for their unique cell walls made of silica. The cell wall of diatoms is intricately designed and is a defining characteristic of this group. - **Fungi**: Fungi have cell walls made primarily of chitin, not silica. - **Bacteria**: Bacterial cell walls are typically composed of peptidoglycan, which does not contain silica. 3. **Conclusion**: Based on the characteristics of the cell walls of the organisms listed, the siliconous cell wall is specifically found in **diatoms**. Thus, the correct answer is **diatoms**.
