Transcript of Golgi Bodies & Lysosomes There are two main types or categories of cells: prokaryotic cells and eukaryotic cells. Both of these types of cells have several things in common. All cells are surrounded by a plasma membrane, which is made of a double layer (a bilayer) of phospholipids. Within this membrane, is the cytoplasm which is composed of the fluid and organelles of the cell.
The Golgi apparatus is an organelle found in DNA-carrying eukaryotic cells. It is one of the largest structures inside the cell. The Golgi apparatus resembles a long, thin ribbon folded on top of itself to create a long, layered central part with curved edges on either end. These internal layers are known as the cisternae, and their size and shape depend on the type of cell.
