name a gas molecule that can diffuse through cell membrane
oxygen & carbon dioxide
how does the concentration gradient affect the rate of diffusion?
the bigger the concentration gradient, the faster the rate of diffusion
what is diffusion?
the movement of particles from an area of high concentration to an area of low concentration.
factors affecting the rate of diffusion:
Concentration, temperature, and pressure affect the rate of diffusion.
Diffusion occurs more quickly when the concentration, temperature, or pressure are high because the particles collide more often.
The size and charge of a substance also affect the rate of diffusion.
how does temperature affect the rate of diffusion?
the higher the temperature, the faster the rate of diffusion because the particles have more energy so they move around faster
what is it meant by a partially permeable membrane?
only allows small molecules can diffuse through it
