BIOL 231 CELL STRUCTURE AND FUNCTION EXAM (UPDATED AND VERIFIED)
Question 1
2..5 pts
True/False:
Metaplastic cells are not better prepared to survive under stressful circumstances.
True
False
Question 2
2..5 pts
True/False:
Hypertrophy can occur under normal and pathological conditions.
True
False
Question 3
2..5 pts
Multiple Choice
Which is NOT true of the cytoskeleton?
It controls shape and movement
Cilia and flagella are microtubule-filled cellular extensions
It includes peroxisomes and proteasomes
Peroxisomes and proteasomes are not part of the cytoskeleton.
Question 4
2..5 pts
Which are true of the cell membrane? Select all that apply.
Controls the transport of materials from the outside fluids to within
The main structural component is made of proteins
Helps with the conduction of electrical currents in nerve and muscle cells
Aids in the regulation of cell growth and proliferation
Question 5
pts
Compare and contrast the two types of gangrenous necrosis.
Your Answer:
Dry gangrene is when the tissue becomes dyhydrated and shrinks back and becomes dark
brown/black in color and the spread of dry gangrene is slow. In wet gangrene the affected area is
cold, swollen, and does not have a pulse, the skin is moist, black and disteneded. Small blisters
blebs on the skins surface where liquefaction occurs and bad order that is caused by bacteria and the
spread of tissue damage is fast.
In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color
changes to dark brown or black. The spread of dry gangrene is slow. It results from a cut off in
arterial blood supply and is a form of coagulation necrosis. In wet gangrene, the affected area
is cold, swollen, and pulseless. The skin is moist, black, and under tension. Blebs form on the
surface, liquefaction occurs, and a foul odor is caused by bacterial action. The spread of
tissue damage is rapid.
