Final answer:

Plasma membranes are selectively permeable, crucial for cell survival, and passive transport is a natural process.


Explanation:

Plasma membranes are selectively permeable, allowing some substances to pass through while preventing others. This selectivity is crucial for the cell's survival. Passive transport is a natural process where substances move from areas of high concentration to low concentration without the cell expending energy.
