PhagocytosisThe pseupodia are also used for feeding.Amoeba sp. engulfs food by phagocytosis.Amoeba sp. is a holozoic organisms which feed on microscopic organisms such as bacteria..The presence of food causes Amoeba advance by extending its pseupodia.The pseupodia encloses the food which is then packaged in food vacoule.The food vacoule fuses with lysosome and the food is digested by hydrolitic enzyme called lysozyme.The resulting nutrients are absorbed into the cytoplasm. Simple Diffusion.Net movement of molecules or ions from a region of higher concentration to a region of lower concentration..Going down concentration gradient until an equilibrium is achieved..The particles are distibuted equally throughout the system.The concentration gradient provides energy to move the molecules into and out of the cells. Osmosis: the diffusion of water.Net movement of freely moving water from a region of lower solute concentration to a region of higher solute concentration through a semi-permeable membrane.//Net movement of water from region higher water concentration to a region of lower water concentration.//Net movement of water from hypotonic region to hypertonic region.Facilitated DiffusionFor water soluble molecules//molecules which are not soluble in lipids (ions, nucleic acid, amino acids and glucose)Carrier ProteinThe carrier protein function by binding to the molecules to pass through the plasma membrane.The mo
