Importance of gaseous and solute diffusion

Diffusion helps living organisms to:

→ obtain many of their requirements

→ get rid of many of their waste products

→ gas exchange for respiration

Examples :-

✔ CO2 uses by plants for photosynthesis is diffused from the air into the leaves, through the stomata (pores at the surface of leaves). There is a lower concentration of CO2 inside the leaf, as the cells are using it up.

✔ O2 (waste product of photosynthesis diffused out in the same way).

✔ Flowering plants use diffusion to attract pollinators like bees.

✔ Some of the products of digestion are absorbed from the ileum of mammals by diffusion.
