5. c. intermediate filaments
Intermediate filaments are part of cytoskeleton, which reinforce cell shape and anchor some cell organelles.
6. a. nucleus
prokaryotic cells do not contain a nucleus, instead they contain a nucleoid.
7. c. plasmodesmata
Plasmodesmata are channels between cells that are next to each other that allow movement of water and sap between the cells.

Question 13 7 pts Which of the following statements accurately describes why an animal cell would be surrounded by an extra cellular matrix instead of a cell wall? Hint: • Extracellular components a video • Textbook chapter 4 under section 4.6 A cell wall would completely isolate the neighboring cells that are found within multicellular organisms, and because of this, it would prevent the ability of those cells to communicate with each other. The polysaccharide cellulose that is found in...
