What is a hypertonic solution?

Back

A hypertonic solution is one where the concentration of a solution outside the cell is higher than the concentration inside the cell.

What role does cholesterol play in the cell membrane?

Back

Cholesterol provides stiffness and structure to the cell's semipermeable membrane.

Front

What is the primary function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.

What is osmosis?

Back

Osmosis is the movement of water molecules through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
