Exam 2 (Practice Test)

Which of the following is a primary function of the plasma membrane?

• regulates which materials enter and leave the cell

• breaks down lipids, carbohydrates, and proteins from foods

• stores water, salt, proteins, and carbohydrates

• keeps the cell wall in place

The Golgi body is a system of membranes that has the function of 

• modifying and packaging proteins for export by the cell

• housing the cell's genetic code

• making proteins using instructions that come from the nucleus

• breaking down and eliminating wastes from the cell

Which of the following is a characteristic of prokaryotes?

• They have a nucleus

• They are smaller than eukaryotes

• They have a brain

• The organelles in their cytoplasm are surrounded by membranes
