• All living organisms are made of cells.

Prokaryotic cells do not have a ____ and their DNA is located in the ____.

• nucleus; cytoplasm

• cytoplasm; nucleus

• cell membrane; cytoplasm

• cell membrane; cell wall

The nucleus has many characteristics and roles in the cell. Which of the following is NOT a role or characteristic of the nucleus?

• The nucleus contains the nucleolus which is involved in DNA synthesis.

• The nucleus is surrounded by the nuclear membrane.

• The nucleus stores genetic information in the form of DNA.

• The nucleus allows RNA and ribosomes to exit via the nuclear pore.

Lysosomes can digest various substances. What would occur if lysosomes did not do their job properly?

• Old macromolecules/organelles will build up in the cell interfering with normal cellular function

• Mutated DNA will build up in the cell interfering with normal cellular function

• Nuclear pores will get clogged up in the cell interfering with normal cellular function

• Channel proteins will get clogged up in the cell interfering with normal cellular function

It was stated in class that the Golgi apparatus (GA) is similar to a mailing system. Predict what would occur if the GA added the incorrect macromolecule (lipid or carbohydrate) to a protein:

• The protein would not go to its proper destination.

• The protein would still go to its proper destination.

• The protein would enter the smooth endoplasmic reticulum.

• The protein would re-enter the rough endoplasmic reticulum.

Chloroplasts are essential to plant cells because they:

• Convert sunlight to carbohydrates

• Convert sunlight to DNA

• Convert carbon dioxide and water to ATP

• Convert sunlight to RNA
