What is the function of the plasma membrane

It helps recognize other cells.
It contains hereditary material.
It helps filter waste inside the cell.
It helps plants maintain their shape.

The function of the plasma membrane is to control the movement of substances in and out of the cell. It is selectively permeable, allowing certain molecules to enter or leave the cell while preventing others from doing so. The plasma membrane also helps maintain the cell's shape and structure.

The correct option is: It helps recognize other cells.

The function of the plasma membrane is to act as a selective barrier that separates the inside of a cell from its external environment. It consists of a phospholipid bilayer with embedded proteins. One of its important functions is to recognize and interact with other cells or molecules in its surroundings. The plasma membrane contains various proteins and receptors that allow for cell signaling and communication with neighboring cells. These interactions are crucial for processes such as cell recognition, immune response, and cell-cell communication.
