Substances will pass in and out of the cell in an uncontrolled manner.

According to articles:

"Membranes form the boundaries of cells and cell organelles. They separate inside from outside and allow compartmentalization of DNA, RNA, proteins, and other molecules or ions. Without membranes, life as we know it would not be possible."
