-excretion of waste
what are the kinds of transport?
-passive (needs no cell energy)
-active (needs cell energy)
diffusion
movement of materials because they want to balance from an area of GREATER concentration TO LESSER concentration
concentration gradient
difference in the concentration of a substance across a space.
passive transport
movement of materials across the cell membrane without cell energy-using the energy of the moving materials.
osmosis
diffusion of water across the cell membrane (water only)
hypotonic solution
solution surrounding the cell having a GREATER concentration than inside the cell.
cytolysis
bursting of a cell
turgor pressure
pressure of water against the cell wall and cell membrane of a plant cell.q
