PRINCIPLES OF BIOLOGY (BIO 123)-
CHAPTER 4 THE CELL EXAM
QUESTIONS AND ANSWERS
Cell Theory - Correct Answers -all living things are made of cells
every living thing is composed of - Correct Answers -1 + cells
mitosis - Correct Answers -cells arise from other cells through replication
2 types of cells - Correct Answers -prokaryotic and eukaryotic
prokaryotic cells - Correct Answers -bacteria and archea
eukaryotic cells - Correct Answers -all other cells other than bacteria and archea
prokaryotes DO NOT have - Correct Answers -bound nucleus (DNA floats free)
prokaryotes DO NOT CONTAIN - Correct Answers -membrane bound organelles
(specialized structure of cell)
eukaryotes have a - Correct Answers -nucleus (that contains DNA)
finished proteins move from the RER in - Correct Answers -transport vesicles to Golgi
complex
Responsibilities of the Rough Endoplasmic Reticulum - Correct Answers -membrane
network of sacs, "rough" embedded with ribosomes, makes more membranes,
ribosomes drop more polypeptide chains into internal spaces of the RER, folds chains
becoming proteins, proteins transferred by vesicles
Smooth endoplasmic reticulum - Correct Answers -"Smooth" no ribosomes, synthesize
lipids and detoxify harmful substances, store calcium for muscle and nervous function,
does not participate in protein synthesis, responsible for making (producing testosterone
and estrogen in ovaries and testes as well as liver which detoxifies substances)
