Diffusion, Osmosis and Active transport

Example of Diffusion in the Small intestine

Digested food products including glucose, amino acids, fatty acids, glycerol and more are diffused from the lumen of the small intestine to the blood and the lymph in villi found covering the walls of the small intestine

Example of Diffusion in the Leaf (OXYGEN)

Oxygen moves from the air spaces between mesophyll cells to the mitochondria in all cells for respiration

Example of Diffusion in the Leaf (CARBON DIOXIDE)

Carbon dioxide moves from air spaces between the mesophyll cells to the chloroplasts in mesophyll cells

Example of Diffusion in the Leaf (WATER VAPOUR)

Water vapour moves from the stomatal pores to the air outside the stomata

Example of Diffusion in the Lungs (OXYGEN)

Oxygen moves from the alveolar air space to the blood in capillaries around alveoli

Example of Diffusion in the Lungs (Carbon dioxide)

Carbon dioxide moves from blood in capillaries around alveoli to alveolar air spaces
