This document contains a series of questions and answers about cell structure. It tests the reader's knowledge about the components found in both prokaryotic and eukaryotic cells, the sizes of different cells and organelles, and other cell biology topics. The reader is prompted to consider each question before viewing the answer.

1. •Take some time to consider the question before
moving to the next slide which offers the correct
answer.
•Write your answer down before you see the actual
answer, this will allow you to test yourself more
effectively.

12. Cell Structure
True or False. The circular single chromosome
that most prokaryotes possess is simply floating
around in the cytoplasm.

13. Cell Structure
True or False. The circular single chromosome
that most prokaryotes possess is simply floating
around in the cytoplasm.
False. Nothing as important as a chromosome is
left to chance! Prokaryotic chromosomes may not
be enclosed in a nucleus, but they are carefully
packaged and anchored in place by a primitive
cytoskeleton. The location of the chromosome is
called the nucleoid.
