diffusion

what is diffusion?

the movement of molecules from an area of high concentration to low concentration

is diffusion an active or passive process?

diffusion is a passive process, meaning it requires no energy

in which states does diffusion occur?

diffusion occurs in gases and liquids

how does diffusion help plants?

diffusion helps plants move gases and liquids in and out for respiration and photosynthesis

what happens to oxygen in the lungs during diffusion?

oxygen moves from the air (high concentration) into the lungs (lower concentration) for respiration

what is the role of diffusion in removing carbon dioxide from the body?

carbon dioxide moves from the blood (high concentration) into the lungs (lower concentration) to be exhaled

how do nutrients get absorbed in the small intestine?

Nutrients move from the small intestine (high concentration) into the bloodstream (lower concentration) through diffusion

what is the significance of water movement in kidney cells through diffusion?

water moves from the bloodstream (high concentration) into kidney cells (lower concentration) to regulate hydration and remove waste

how does oxygen move in body tissues?

oxygen moves from the bloodstream (high concentration) into body tissues (lower concentration) via diffusion to support cellular respiration

what occurs during gas exchange in leaves?

carbon dioxide moves into the leaf (lower concentration) from outside air (high concentration) through diffusion

what is transpiration in relation to diffusion?

water vapour moves out of the leaf (high concentration) into the air (lower concentration) via diffusion, helping to cool the plant

how do roots absorb nutrients from the soil?

nutrients move from the soil (high concentration) into the root cells (lower concentration) via diffusion

what supports respiration in roots?

oxygen from the soil moves into root cells via diffusion, where the concentration is lower

what does water movement in plants achieve?

water moves from the soil (high concentration) into root cells (lower concentration) to help maintain water balance
