Life in the cell is busy. I have a busy job. I store products like proteins. I am important for the exporting of needed substances in and out of the cell. I transport materials needed between organelles and the plasma membrane. I’m a vesicle. I am a fluid-filled, membrane-bound body. I work with the the Golgi apparatus. The Golgi apparatus packages the modified proteins and lipids. I store them. I get rid of waste in the cell. When there is too much worn out organelles I get rid of them. Without me the cell wouldn’t survive.
