State whether the following statement is true or false.
An extracellular matrix helps some cells to adhere to neighbouring cells.
A. True
B. False

Answer

To determine whether the statement "An extracellular matrix helps some cells to adhere to neighbouring cells" is true or false, we can analyze the components and functions of the extracellular matrix (ECM).

### Step-by-Step Solution:

1. **Understanding Extracellular Matrix (ECM)**: The extracellular matrix is a complex network of proteins and carbohydrates that exists outside of cells. It provides structural and biochemical support to surrounding cells.

2. **Components of ECM**: The ECM is primarily composed of macromolecules such as collagen, glycoproteins, and proteoglycans. These components play a crucial role in maintaining the structure and function of tissues.

3. **Function of ECM**: One of the key functions of the ECM is to provide structural support to cells. It helps in anchoring cells in place and facilitates communication between them.

4. **Cell Adhesion**: The ECM contains specific molecules that promote cell adhesion. These molecules allow cells to stick to one another and to the ECM itself, facilitating the formation of tissues.

5. **Conclusion**: Since the extracellular matrix indeed helps cells adhere to one another and plays a significant role in tissue formation, the statement is true.

### Final Answer:
A. True
