osmosis

diffusion of water from an area of greater to lesser concentrations (depends on water and solutre concentrations)

solution

solutes + solvents

example of a solute

sugar

water

hypertonic solution

high concentrated solution

hypertonic solution has () solutes and () solvent

high, low

hypotonic solution

low concentrated solution

hypotonic solution has () solutes and () solvent

low, high

when the solution inside the cells is hypertonic relative to its environment, water will move () the cell

into

when the solution inside the cell is hypotonic relative to its environment, water will move () the cell

out of

isotonic

same inside/outside (water/solutes won't move)

passive transport

doesn't use chemical energy

what are forms of passive transport

osmosis, diffusion

active transport

uses chemical energy (ATP)

homeostasis

taking in nutrient and exporting wastes
