Diffusion and Osmosis

These flashcards cover key vocabulary terms and definitions related to diffusion, osmosis, and cellular processes.

Concentration Gradient

Difference in concentration between two solutions.

Diffusion

Movement of solute particles from an area of high concentration to an area of low concentration.

Brownian Movement

Random movement of particles in solution due to molecular collisions.

Water Potential

The potential energy of a volume of water, affected by solute concentration.

Osmosis

The movement of water molecules from low solute concentration to high solute concentration.

Tonicity

Describes the relationship between two solutions regarding solute concentrations.

Hypotonic Solution

Solution with a low concentration of solute particles compared to another solution.

Hypertonic Solution

Solution with a high concentration of solute particles compared to another solution.

Isotonic Solution

Solutions with equal solute concentrations.

Turgor Pressure

Pressure in the vacuole that pushes against the cell wall in plants, helping them maintain structure.
