The correct Answer is:
To solve the question "Which one of the following acts as cementing material?", we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks for the material that serves as a cementing agent between cells. This is typically related to the structure of plant cells. 2. **Identify Key Terms**: The term "cementing material" refers to a substance that binds or holds cells together. In plant cells, this is often associated with the middle lamella. 3. **Recall the Function of Middle Lamella**: The middle lamella is a layer that exists between the cell walls of adjacent plant cells. It is primarily responsible for adhering cells together. 4. **Determine the Composition of Middle Lamella**: The middle lamella is mainly composed of pectin, which is a polysaccharide. It is crucial for cell adhesion and allows for cell wall expansion during growth. 5. **Evaluate the Options**: - **Option 1: Calcium salt** - This is not specifically related to the cementing function. - **Option 2: Pactic acid** - This is incorrect as it does not serve as a cementing material. - **Option 3: Calcium Pectate** - This is the correct answer as it is a component of the middle lamella and acts as the cementing material between cells. - **Option 4: Other options** - Evaluate them similarly to confirm they do not fit the criteria. 6. **Select the Correct Answer**: Based on the evaluation, the correct answer is **Calcium Pectate** (Option 3), as it is the cementing material that binds adjacent cells together. ### Final Answer: The correct answer is **Calcium Pectate** (Option 3). ---
