Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.

Yet as we mentioned before, such barriers can not be so rigid and impenetrable that they prevent movement of materials across the membrane. Let's turn our attention to proteins that associate with the membrane and confer added functionalities to it.

Thylakoids, grouped as grana, contain essential proteins for photosynthesis. The surrounding stroma holds enzymes for the dark reactions and chloroplast genomes, while some proteins are created in the cytoplasm and transported into the chloroplasts.
