Answer

Brief Explanations:

The plasma membrane is a selectively - permeable barrier. It controls the movement of substances like ions, nutrients, and waste in and out of the cell to maintain the cell's internal environment. Energy production is mainly by mitochondria, cell division involves structures like centrioles and spindle fibers, protein synthesis occurs in ribosomes, and while the membrane offers some protection, its main function is regulation of substance movement.

Answer:

Regulates the movement of substances in and out of the cell.
