- Lysosomes are made up of digestive enzymes that are in a membranous sac

- Rough ER is what makes the enzymes and membranes of lysosomes then they are transferred to the Golgi apparatus to be processed

- In eukaryotic cell lysosomes are the main theme of compartmentalization

- In the membrane of lysosomes there is a compartment where the digestive enzymes are stored in a safe acidic environment away from the rest of the compartments of the cell

- Lysosomes have different digestive functions:

- They are recycling centers of animal cells

- Damaged organelles and small portions of cell fluids become enclosed in membrane vesicles. When this happens a lysosome fuses with the damaged vesicles and it destroys the bad contents and recycles and digests it so it can be available to be reused

- With lysosomes a cell can continually renew itself

- Lysosomes fuse with food and breaks down the food releasing all of the nutrients of the food into the cell
