1. Animal cells have unique organelles called _____ that are
composed of structures called ____.

called the __________.
Nucleoid
7. The walls of plant cells are largely composed of polysaccharides
and proteins that are synthesized _____.
In the rough endoplasmic reticulum and in the Golgi apparatus
8. Microfilaments function in cell motility including ______.

adjacent cell through __________.
Plasmodesmata
11. The function of the rough endoplasmic reticulum (RER) is __.
To synthesize proteins that are secreted as glycoproteins
12. Which statement about the cytoskeleton is true?
Components of the cytoskeleton often mediate the movement of
organelles within the cytoplasm.

DNA molecules associated with their inner membranes
14. Which of the following is false in respect to cells'
chromosomes?

15. The endosymbiont theory explains the origins of ________.
Mitochondria and chloroplasts
16. In terms of cellular function, what is the most important
difference between prokaryotic and eukaryotic cells?
Eukaryotic cells are compartmentalized, which allows for
specialization.
17. _____ are membrane-bound metabolic compartments that
specialize in the production of hydrogen peroxide (H2O2) and its
conversion to water.
Peroxisomes

20. Your intestine is lined with individual cells. No fluids leak
between these cells from the gut into your body. Why?
The intestinal cells are bound together by tight junctions.
21. Cilia and flagella move due to the interaction of the
cytoskeleton with which of the following?
