osmosis

what is osmosis?

the movement of water from an area of low solute concentration to an area of high solute concentration across a semi-permeable membrane

what type of process is osmosis?

a passive process that does not require energy

how do root hair cells absorb water?

water moves into root hair cells because the soil has a lower concentration of solutes compared to the cells

what happens to red blood cells in pure water?

water moves into red blood cells, causing them to swell and possibly burst due to higher solute concentration inside the cells

how do kidneys use osmosis?

water from urine moves into the blood to maintain fluid balance because the blood has a higher solute concentration

what effect does saltwater have on animal cells?

water moves out of the cells, causing them to shrink and become flaccid due to higher solute concentration in saltwater

how does osmosis work in the digestive system?

water moves into cells from the lower solute concentration in the digestive system to hydrate cells and assist nutrient absorption

what process replaces water lost through evaporation in plants?

osmosis draws water from roots to replace lost water during transpiration

what protects plant cells from bursting when water enters them?

the cell wall provides structure and prevents bursting even as they swell from water uptake

what role does osmosis play in photosynthesis for plants?

osmosis helps root hair cells take in water, which is essential for photosynthesis and hydration
