Is it true that the cell membrane plays an important role in cell communication and cell-to-cell adhesion?

The cell membrane is composed of a variety of proteins, including receptors, which can bind to signaling molecules outside the cell and transmit signals into the cell. This allows for communication between cells and the coordination of cellular processes. Additionally, the cell membrane also contains adhesion molecules, which allow cells to bind to one another and form tissues. The cell membrane also contains channels and pumps that help to control the movement of ions and molecules across the membrane, which is important for maintaining homeostasis and cell signaling.
