What does the nucleus contain?

The nucleus contains chromatin which is made of proteins and DNA.The nucleus also contains the nucleolus which makes ribosomes

What is different about the membrane of the mitochondria?

The mitochondria has a double membrane;the inner membrane is folded to produce a structure called a cristae. The cristae contains what is called a matrix which contains the enzymes involved in respiration.

What are vesicles and where are they found?

Vesicles are used to transport materials. They can be used in exocytosis is which is when vesicles take substances to the cell surface membrane and discard of them outside of the cell. Endocytosis is when materials are brought into the cell from outside

What is the role of the Golgi body?

It makes liposomes and processes and packages new proteins and lipids.

4 of 10

When are the centrioles used?

During cell division

5 of 10

What is the difference between the rough and smooth ER?

The rough ER contains ribosomes but the smooth ER doesn't

6 of 10

What are lysosomes?

They are round organelles which contains digestive enzymes to break down any unwanted substances in the cell or any worn out organelles.

7 of 10

What happens at the ribosomes?

This is the site where proteins synthesis occurs.

8 of 10

What is the function of the smooth ER?

The smooth ER is involved in the synthesising and processing of lipids.

What is the function of the rough ER?

The rough ER is involved in the folding and processing of proteins.
