Questions: Function of the extracellular matrix Which of the following is NOT a function of the extracellular matrix in animal cells? Multiple Choice provides a channel for water and ion flow between adjacent cell walls permits communication between the extracellular matrix and the cells helps cells have flexibility creates a variety of consistencies for cells to live in, from flexible cartilage to solid bone enables cells to migrate along intracellular fibers

The answer is the first one: provides a channel for water and ion flow between adjacent cell walls.

Explanation for each option:

1. Provides a channel for water and ion flow between adjacent cell walls: This is incorrect because the extracellular matrix (ECM) in animal cells does not provide channels for water and ion flow between cell walls. This function is more related to plant cells, where plasmodesmata serve as channels between cell walls.

2. Permits communication between the extracellular matrix and the cells: This is correct. The ECM plays a crucial role in cell signaling and communication, allowing cells to respond to changes in their environment.

3. Helps cells have flexibility: This is correct. The ECM contributes to the mechanical properties of tissues, including flexibility, by providing structural support and elasticity.

4. Creates a variety of consistencies for cells to live in, from flexible cartilage to solid bone: This is correct. The ECM is responsible for the diverse physical properties of tissues, ranging from the flexibility of cartilage to the rigidity of bone.

5. Enables cells to migrate along intracellular fibers: This is correct. The ECM provides a substrate for cell migration, which is essential for processes like wound healing and development.

In summary, the function that is NOT associated with the extracellular matrix in animal cells is providing a channel for water and ion flow between adjacent cell walls.
