Biology

The correct answer is: B.Provides a strong structure to keep the cell stiff and solid.

The cell (plasma) membrane does not provide a strong, stiff structure to the cell. Instead, the membrane is fluid and flexible, allowing the cell to maintain its shape and move. The primary functions of the cell membrane include:

1.Cell-to-cell communication: The membrane contains proteins that help cells recognize and communicate with one another, often using receptors and signaling molecules.

2.Cell recognition: Glycoproteins and glycolipids on the cell membrane are involved in recognizing other ce...
