Cell basics- Lysomes
What are the properties of a lysosome?
Lysosomes are organelles found inside plant and animal cells, but not in bacteria cells.
Updated Version
https://youtu.be/jvfDdZtD5SQ

They are important because lysosomes help break down old cell parts and and digest materials brought into the cell. They might be used to digest food or break down the cell when it dies.
Lysosomes have a single membrane and are filled with digestive enzymes.
A lysosome is created at the Golgi apparatus.
The proteins of the lysosome are created at the rough ER and are packed in a vesicle that is transported to the golgi apparatus. The golgi apparatus uses these proteins to make digestive enzymes and creates a vesicle that pinches off.
This vesicle is a lysosome
Lysosomes are found in the cytoplasm.
When materials are brought into the cell lysosomes can attach to these objects and begin to break them down.
Lysosomes will also break down other organelles like mitochondria if the cell does not have any food or the mitochondria is working improperly.
Lysomes will even digest bacteria that enters the cell.
