Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is a semipermeable membrane?

Back

A semipermeable membrane allows certain molecules to pass through while blocking others.

Front

How does a hypotonic solution affect a cell?

Back

A hypotonic solution causes water to enter the cell, potentially leading to swelling or bursting.
