Synthesis of cell wall material takes place in :–

Options

A. Dictyosome
B. Mitochondria
C. Lysosome
D. E.R.

Answer

To answer the question "Synthesis of cell wall material takes place in:", we need to analyze the options provided and identify where cell wall synthesis occurs.

### Step-by-Step Solution:

1. **Understanding Cell Wall Composition**: The cell wall is primarily made of polysaccharides, proteins, and other materials. In plant cells, the main component is cellulose.

2. **Identifying the Key Organelles**:
- **Dictyosome (Golgi Apparatus)**: This organelle is involved in the synthesis and secretion of cell wall materials, particularly in plant cells. It consists of flattened membrane-bound sacs and is responsible for processing and packaging proteins and polysaccharides.
- **Mitochondria**: These are the powerhouse of the cell, involved in cellular respiration and energy production, not in cell wall synthesis.
- **Lysosome**: Known as the "suicidal bag" of the cell, lysosomes are involved in digestion and waste removal, not in the synthesis of cell wall materials.
- **Endoplasmic Reticulum (ER)**: The ER is involved in the synthesis of proteins and lipids but does not directly synthesize cell wall materials.

3. **Conclusion**: Based on the functions of the organelles listed, the correct answer is that the synthesis of cell wall material takes place in the **Dictyosome** (Golgi Apparatus).

### Final Answer:
The synthesis of cell wall material takes place in **Dictyosome** (Golgi Apparatus).
