Which of the following would a microbiologist be surprised to find within a bacterial cell?
(a) plasmids (b) internal membranes (c) a circular chromosome (d) ribosomes.

(b) internal membranes

Explanation:

This is because prokaryotes do not have internal membranes. The other components -- plasmids, circular chromosomes (plasmids), and ribosomes, are all in bacterial cells, however.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
