What is the functional connection between the nucleolus, nuclear pores, and the nuclear membrane? a. Subunits of ribosomes are assembled in the nucleolus and pass through the nuclear membrane via the nuclear pores. b.

A plant was grown in a test tube containing radioactive nucleotides, the molecules from which DNA is built. Later examination of dividing cells in the plant showed the majority of the radioactivity to be concentrated in the _____. a. b. c. d. e. rough endoplasmic reticulum lysosome smooth endoplasmic reticulum central vacuole nucleus 9. Which of the following categories best describes the function of the rough endoplasmic reticulum? a. b. c. d. e. breakdown of complex foods energy processing manufacturing structural support of cells information storage 10. A researcher made an interesting observation about a protein made by the rough endoplasmic reticulum and eventually used to build a cell’s plasma membrane. The protein in the plasma membrane was actually slightly different from the protein made in the ER. The protein was probably altered in the ______. a. b. c. d. e. Golgi apparatus smooth endoplasmic reticulum plasma membrane transport vesicles rough endoplasmic reticulum 11. Which of the following sequences represents the order in which a protein made in the rough endoplasmic might move through the endomembrane system? a. b. c. d. e. lysosome; plasma membrane Golgi apparatus; mitochondria Golgi apparatus; vacuole plasma membrane; nuclear envelope nuclear envelope; lysosome 12. A protein that ultimately functions in the plasma membrane of a cell is most likely to have been synthesized ______. a. b. c. d. e. on ribosomes on the nuclear envelope on free cytoplasmic ribosomes in the rough endoplasmic reticulum in the mitochondria in the plasma membrane 13. Which one of the following statements about chloroplasts and mitochondria is true? a. b. c. d. e.
