II. THE PROKARYOTIC CELL: BACTERIA

B. PROKARYOTIC CELL ANATOMY

3. STRUCTURES LOCATED WITHIN THE CYTOPLASM

The overall purpose of this Learning Object is to list the various cellular components that are often found within bacterial cytoplasm.

LEARNING OBJECTIVES FOR THIS SECTION

In this section on Prokaryotic Cell Anatomy we are looking at the various anatomical parts that make up a bacterium. As mentioned in the introduction to this section, a typical bacterium usually consists of:

• a cytoplasmic membrane surrounded by a peptidoglycan cell wall and maybe an outer membrane;
  
• a fluid cytoplasm containing a nuclear region (nucleoid) and numerous ribosomes; and
  
• often various external structures such as a glycocalyx, flagella, and pili.
  

We will now look at the following cellular components located within the cytoplasm.

a. cytoplasm
b. DNA located in the nucleoid
c. plasmids and transposons
d. ribosomes
e. endospores
f. organelles for photosynthesis
