3. what material does the nucleus contain? what is the purpose of this material? the nucleus contains "the cell's genetic material, dna." dna makes protein molecules to with almost every cellular process. 4. using evidence from the text, describe the purpose of the cell membrane. 5. how do the two types of endoplasmic reticulum differ? 6. using evidence from the text, describe the purpose of the golgi complex. 7. based on this excerpt, summarize the job of mitochondria. excerpt: "about the size of pickup trucks from where you're floating, the organelles called mitochondria convert energy from your food into adenosine triphosphate, or atp, to power biochemical reactions. a typical cell burns through 1 billion molecules of atp every 1 to 2 minutes."

3. The nucleus contains "the cell's genetic material, DNA." DNA makes protein molecules to help with almost every cellular process.
4.The membrane protects the cell's internal environment—a thick brew called the cytosol made of salts, nutrients and proteins that accounts for about half the cell's volume (organelles make up the rest).
5.The ER sends newly made proteins and lipids to the Golgi complex, a short and narrow structure inside the cytosol. The Golgi complex processes them and sends the molecules to their final destinations inside or outside the cell.
6.The Golgi complex processes them and sends the molecules to their final destinations inside or outside the cell
7.Mitochondria converts energy from our food into adenosine triphosphate, or ATP, to power biochemical reactions

Hope this helped!, and please correct me if i'm wrong. i tried my best. i got the same assignment!
