Where can ribosomes be found in the cell?

• On the Golgi apparatus

• Inside the nucleus

• On the rough ER and in the cytoplasm

• On the smooth ER

What is the main function of the rough ER?

• To break down unwanted substances

• To produce lipids

• To modify cellular products

• To produce phospholipids and proteins

How can you distinguish the Golgi apparatus from the ER?

• It is closer to the nucleus

• It has ribosomes on it

• It produces ATP

• It is further from the nucleus and has no ribosomes

What is the role of lysosomes in the cell?
