Enumerate the significance of diffusion in plants ?

Explanation

1. Gaseous exchange of `O_(2)` and `CO_(2)` between the atmosphere and stomata of leaves takes place by the process of diffusion.
2. `O_(2)` is absorbed during respiration and `CO_(2)` is absorbed during photosynthesis.
3. In repiration water vapour from intercellular spaces diffuses into the atmosphere through stomata by the process of diffusion.
4. The diffusion of ions of mineral salts during passive absorption also takes place by this process.
