A) protect the internal aspect of the cell from substances outside the cell.
B) breaking down and digesting unwanted substances within the cell.
C) binding specific molecules arriving from outside of the cell.
D) selectively controlling the substances that enter or leave the cell.
E) moving specific substances from outside the cell to inside the cell.

Accepted Answer

The plasma membrane is responsible for protecting the cell from substances outside the cell, binding specific molecules, selectively controlling substances entering or leaving the cell, and moving specific substances into the cell. Breaking down and digesting substances within the cell is not a function of the plasma membrane. This is the role of the lysosomes.
