These are membranes within cells that divide the cell into different compartments, or organelles.
This is an internal membrane system involved in protein and lipid synthesis. It's like the factory area of our house where goods are produced.
An organelle composed of stacked layers of flat sacs (cisternae) involved in modifying, sorting, and packaging proteins and lipids. It's like the post office inside our house where items get packaged and labeled for delivery.
Small membrane-bound sacs that transport materials within the cell. They're like delivery trucks carrying goods from one part of our house to another.
