Animals as well as all other organisms than bacteria and blue green algae are eukaryotic. see also: BIOS-1053 Study Guide One • Explain various mechanisms involved in the movement of materials across biological membranes. • Osmosis is the movement of water molecules from an area of high to an area of low concentration through a differentially permeable membrane. It is termed a type of passive transport and requires no expenditure of energy. • Endocytosis, pinocytosis and phagocy
