The cell uses membranes to build compartments within the cell and to create the border between the cell and its environment.

The cell uses membranes to build compartments within the cell and to create the border between the cell and its environment. Membranes also make up organelles, which are areas of the cell where specific mechanisms can occur. How do the plasma membrane and its component organelles work to protect the cell while allowing it to interact with its environment? Be sure to draw examples from the previous modules.
