BIO 141 CELL STRUCTURES EXAM
QUESTIONS AND ANSWERS
Name the parts of the nucleus. - Correct Answers -nuclear envelope, nuclear pores,
nucleolus, chromatin (red stringy)
What is the function of the rough endoplasmic reticulum? - Correct Answers -produces
secretory proteins
What is the function of the smooth endoplasmic reticulum? - Correct Answers -makes
steroids and lipids
Golgi apparatus - Correct Answers -modifies and packages stuff that leaves the cell;
looks like purple cabbage or stack of exploding cartoon pancakes
vesicles - Correct Answers -little membrane-bound bubbles transporting substances
leaving the cell
What is the distinguishing feature of metaphase called? What does it look like? - Correct
Answers -the metaphase plate; dark line of chromosomes lined up in the center
between the two spindle poles; nuclear membrane has disappeared
What does anaphase look like? - Correct Answers -the metaphase plate splits in half
(the chromosomes split at the centromeres and the sister chromatids separate as they
are pulled to opposite poles); two lines of chromatids are visible as they move toward
the spindle poles
At what point in mitosis is the cleavage furrow visible? - Correct Answers -early
telophase
lysosomes (purple spheres) - Correct Answers -vesicles containing digestive enzymes
that digest things inside the cell (digest food and dead material)
peroxisomes (yellow spheres) - Correct Answers -...
centrioles - Correct Answers -organize the mitotic spindles which enable the cell to
divide; two in each cell next to nucleus, look like twizzlers
What are the stages of mitosis? - Correct Answers -ipmat
interphase, prophase, metaphase, anaphase, telophase
