1) what is the function of a cell’s selectively permeable plasma membrane?

The plasma membrane is a semi-permeable membrane that allows the movement of a molecule from inside to outside of the cell and vice versa.

Further Explanation:

All the eukaryotes and prokaryotes consist of the plasma membrane. Some plants and bacteria consist of a cell wall that is attached to the cell membrane. The fluid mosaic model describes the membrane of the cell. The membrane is also called a cell membrane. The cell membrane is made up of protein, phospholipids, and cholesterol. Phospholipids make cell membrane permeable and allow diffusion of molecules in the cell and outside of the cell.

The plasma membrane performs many functions in the cell. They act as a barrier to separate the outer environment from the cell. They provide structural support in the cell and make cell flexible. Carbohydrates present in the cell help in the signaling of a molecule. They transport toxic molecules outside the cell by the semi-permeable membrane and prevent the cell from a toxic chemical.
