The examples of diffusion in plants are:

  1. The uptake of water and nutrients from the soil by the roots
  2. The distribution of nutrients and water to all the parts of the plant
  3. Diffusion of Carbon Dioxide into the leaf of the plants during photosynthesis
  4. Release of oxygen out of the stomata of the leaf

The uptake of water and nutrients from the soil via the roots is through another process known as OSMOSIS. Not to be confused with DIFFUSION.

Osmosis: The net movement of water molecules from a region of higher water potential (eg. a dilute solution) to a region of lower water potential (eg. a concentrated solution) through a partially permeable membrane.

Diffusion: The net movement of particles from a region of higher concentration to a region of lower concentration down or along a concentration gradient as a result of their random movement,
