Passive Transport
This paragraph is about passive transport and all of its specified categories. movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. meaning that no energy is put in to the movement of the organelles and other molecules across the cytoplasm and through the cell membrane which provides passage for cells. It is unlike active transport, it does not require an input of cellular energy. passive transport is just like pushing a boulder down the hill it requires literally no energy or force doing that because gravity just takes it. there are four different types of passive diffusion simple, facilitated, filtration, and osmosis. Facilitated diffusion, also called carrier-mediated osmosis, is the movement of molecules across the cell membrane via special transport proteins that are embedded within the cellular membrane.Osmosis is the movement of water molecules across a selectively permeable membrane. Filtration is movement of water and solute molecules across the cell membrane due to hydro static pressure generated by the cardiovascular system. Diffusion is the net movement of material from an area of high concentration to an area with lower concentration. this is all there really is to passive transports, other words the basics.
