Answer:

The correct phrases that describe the plasma membrane are: a and d.

Explanation:

All cells contain a membrane that separates and protects their chemical components from the extracellular environment. The plasma membrane is the structure that defines the cell. It works as a barrier between the interior of the cell and its environment as it allows the entry and exit of molecules through it. This passage of molecules is a phenomenon called permeability. The cell membrane is characterized by being a dynamic structure, fluidity being one of its most important characteristics.
