Movement across the cell membrane that does not require energy from the cell is called

• active transport

• passive transport

• mass transport

A difference in the concentration of a substance across a space or between two solutions is called

• concentration gradient

• potential

• equilibrium

• balance

It is a type of passive transport which involves the movement of substances from a high concentration area to a low concentration area.

• effusion

• diffusion

• concentration gradient

Diffusion is the movement of a substance from an area of low concentration to an area of higher concentration.

• True

• False

Osmosis is a process that requires energy to transport substances in and out of the cell.

• True

• False

When molecules are evenly distributed throughout the cell, they are said to be in

• homeostasis

In osmosis, free water molecules move from a higher concentration of solutes to a lower concentration of solutes.
