Framework elements take part in

Options

A. Synthesis of protoplasm
B. Synthesis of cell wall
C. Formation of storage products
D. Both B and C.

Answer

**Step-by-Step Solution:**

1. **Identify Framework Elements**: The framework elements primarily include carbon (C), hydrogen (H), and oxygen (O). These elements are fundamental to the structure and function of biological molecules.

2. **Understand Their Role**:
- Carbon, hydrogen, and oxygen are essential for forming the structural framework of cells.
- They are integral components of various biological molecules, including carbohydrates, proteins, lipids, and nucleic acids.

3. **Synthesis of Cell Wall**:
- The cell wall is primarily composed of cellulose, which is made up of carbon, hydrogen, and oxygen.
- Therefore, framework elements play a crucial role in the synthesis of the cell wall.

4. **Formation of Storage Products**:
- Storage products such as glycogen and starch are also composed of carbon, hydrogen, and oxygen.
- These elements are essential for the synthesis of these storage molecules, which provide energy reserves for the cell.

5. **Protoplast Synthesis**:
- Protoplasts refer to the living part of the cell, excluding the cell wall.
- While framework elements are important for overall cellular structure, they do not directly participate in the synthesis of protoplasts.

6. **Conclusion**:
- Based on the roles of framework elements, they are involved in the synthesis of the cell wall and the formation of storage products, but not in the synthesis of protoplasts.
- Therefore, the correct answer is both B (synthesis of cell wall) and C (formation of storage products).

**Final Answer**: Both B and C (synthesis of cell wall and formation of storage products).
