absorbing mineral ions and water Flashcards
what does diffusion transport?
water, carbon dioxide and oxygen
what does osmosis transport?
water
what does active transport transport?
sugars, amino acids, inorganic and organic ions
what is the concentration gradient?
when particles is high is one area than the other
why is active transport needed to transport molecules?
often substances have to be moved from low concentration to high concentration against a concentration gradient. active transport is the process that is required to move molecules against a concentration gradient
how do molecules move by osmosis?
from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules through a cell’s partially permeable membrane
