Diffusion is the movement of particles from a region where they are in high concentration to a region where they are in low concentration, and is one of the ways substances can move across the cell ...

Many photosynthetic microorganisms are able to detect light and move towards optimal intensities. This ability, known as phototaxis, plays a major role in ecology by affecting natural phytoplankton ...

Diffusion Substances move from a high to a lower concentration down a concentration gradient Carbon dioxide, oxygen, water, food substances, wastes, eg urea No Osmosis Water moves from a high to a ...

The study of thermal diffusion and the Soret effect in fluid mixtures provides critical insights into the coupling between heat and mass transfer. In systems subjected to temperature gradients, ...
