Transport In Plants

Question 1

Diffusion

Answer 1

1. The movement of ions or molecules from the region of higher concentrations to the region of lower concentrations.
2. The rate of diffusion depends upon size and nature of molecules small molecules move faster than large ones and vice versa.
3. The rate of diffusion is high at high temperature.
4. Greater the difference in concentration (gradient of concentration) and shorter the distance b\w 2 regions greater will be the rate of diffusion.
