The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Middle Lamella**: The middle lamella is a layer that acts as a cementing substance between the cell walls of adjacent plant cells. It is crucial for maintaining the structural integrity of plant tissues. 2. **Composition of Middle Lamella**: The middle lamella is primarily composed of pectic substances. These pectins are polysaccharides that help in binding cells together. 3. **Key Elements in Middle Lamella**: The main elements that are necessary for the formation of the middle lamella are calcium and magnesium. These elements are found in the form of calcium pectate and magnesium pectate, which are essential for the stability and function of the middle lamella. 4. **Identifying the Correct Element**: Among the options provided (calcium, zinc, potassium, copper), the element that is specifically necessary for the middle lamella is calcium. While magnesium also plays a role, the question specifically asks for an element, making calcium the most appropriate answer. 5. **Conclusion**: Therefore, the element necessary for the middle lamella is **calcium**.
