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?

• To contain digestive enzymes that break down unwanted substances

• To organize microtubules during cell division

• To build proteins

• To produce energy

What is the function of centrioles in animal cells?

• To modify cellular products

• To increase surface area for absorption

• To produce lipids

• To organize microtubules during cell division

What is the nucleolus responsible for?

• Building ribosomes

• Breaking down unwanted substances

• Transporting chemicals in and out of the cell

• Modifying cellular products
