The membrane component that provides cell identity is glycoproteins, which are proteins with carbohydrate chains attached. These glycoproteins play a crucial role in cell recognition and communication by forming specific markers on the cell surface. They help the immune system distinguish between self and non-self cells, facilitating processes like tissue recognition and immune response. Additionally, glycolipids also contribute to cell identity by serving similar functions in cell signaling and recognition.
The carbohydrates help identify chemical signals and define the characteristics of the cell.

No, the cell wall and cell membrane are separate structures. The cell wall is a rigid layer found outside the cell membrane in plant cells that provides structure and support, while the cell membrane is a semi-permeable barrier that regulates what enters and exits the cell.

The cell membrane regulates what enters and exits the cell by controlling the passage of molecules. It also provides protection to cell organelles by surrounding them and maintaining their internal environment.
