What is the simple precurser or of middle lamella?

Answer

### Step-by-Step Text Solution:

1. **Understanding Middle Lamella**: The middle lamella is a layer that exists between the cell walls of two adjacent plant cells. It plays a crucial role in cell adhesion and maintaining the structural integrity of plant tissues.

2. **Composition of Middle Lamella**: The middle lamella is primarily composed of pectins, which are polysaccharides that help in binding the cells together.

3. **Simple Precursor of Middle Lamella**: The simple precursor of the middle lamella is primarily calcium pectate. Calcium ions interact with pectin molecules to form calcium pectate, which is essential for the stability and structure of the middle lamella.

4. **Function of Middle Lamella**: The middle lamella not only acts as a cementing substance between cells but also plays a role in cell signaling and communication.

5. **Conclusion**: Therefore, the simple precursor of the middle lamella is calcium pectate, which is formed from pectin and calcium ions.
