Diffusion Flashcards
Dissolved Substances and Gases can Move Into and Out of Your Cells Across the Cell _____________.
Membrane.
What is Diffusion?
The Spreading out of the Particles of a Gas, or any Substance in Solution (a Solute).
What does the Net Movement in Diffusion Result in?
The Net Movement is From an Area of Higher Concentration to an Area of Lower Concentration of the Particle.
Diffusion Takes Place because of the Random Movement of the ____________.
Particles.
If there’s a Big Difference in ________________ Between Two Areas, Diffusion will Take Place Quickly!
Concentration.
Net Movement Equation?
Net Movement = Particles Moving In - Particles Moving Out.
The Greater the Difference in Concentration, the Faster the Rate of Diffusion. This is Called the Concentration ____________.
Gradient.
An Increase in Temperature Means the Particles in a Bas or a Solution Move Around More ___________.
Quickly.
Dissolved Substances Move Into and Out of Your Cells by Diffusion Across the Cell ____________.
Membrane.
The Oxygen You Need For _______________ Passes From the Air in Your Lungs into Your Red Blood Cells through the Cell Membrane by Diffusion.
Respiration.
Individual Cells may be Adapted to Make Diffusion Easier and More ________. The Most Common Adaptation is to Increase the Surface Area of the ________ Membrane.
Rapid…Cell…
