Water moves from roots to leaves via capillary action, aided by cohesion, adhesion and tiny plant vessels.

Plants absorb water and nutrients from the soil, transporting them to the leaves via their vascular system.

Guard cells surround stomata, regulating transpiration rate by controlling the stomatal aperture size.

Stomata are tiny pores on plants that enable gas exchange and water vapor release.

Evaporation in plants, primarily through transpiration, facilitates water vapor movement from plants to the atmosphere.

Diffusion regulates the movement of crucial electrolytes like sodium and potassium to maintain cellular fluid balance.

Drug absorption involves active ingredients diffusing through cell membranes or capillaries into the bloodstream.

Hormones, as chemical messengers, use diffusion to move through the bloodstream and affect target cells.

Diffusion is crucial in cells for transporting nutrients, oxygen, and removing waste products.

Kidneys filter waste like urea and ions from blood through diffusion process for excretion.
