1. Why is diffusion important for living organisms?

2. Define concentration gradient.

3. What is the effect of concentration gradient on the rate of diffusion?

4. What is the effect of surface area on the rate of diffusion?

Answer 1

1. because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products.

2.The difference in the concentration of a substance between two areas is called the concentration gradient . The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse. The direction of diffusion is said to be 'down' or 'with' the concentration gradient.

3.The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.

4.The greater the surface area, the faster the rate of diffusion.
