Cells in the small intestine engulf fat droplets by pinocytosis. Phagocytosis is the process by which cells engulf solid particles. The mircobe, trapped in the in the vacuole fuses with lysosomes. Exocytosis Exocytosis is the process by which large molecules held within the cell are transported to the external environment. The process by which these molecules are transported is the golgi apparatus holds the secretions inside the fluid filled membranes.
Small vesicles break off and move toward the cell membrane.
The vesicles fuse with the cell membrane and the fluids are released. The movement of materials across a cell membrane without using cell energy is call passive transport. There are three types of passive transport they are diffusion, osmosis and facilitated diffusion. Diffusion Diffusion is the movement of a molecule form where there is high concentration to where there is a lower concentration. You can experience diffusion by opening a bottle of perfume and the particles well move into the surrounding air until the air has reached equilibrium.
