Prokaryote Practice
Name:
As we know, there are two main categories of cells: prokaryotic and eukaryotic. There are many differences
between these groups of cells. Prokaryotes are grouped in the Monera kingdom while eukaryotes can be from any of the
other kingdoms. Can you name the other kingdoms? Prokaryotes evolved much earlier and are less organized than
eukaryotes because they donít have membrane bound organelles or a nucleus. Meaning, the material inside of a
prokaryote is just a jumbled mess in the cytoplasm, but amazingly prokaryotic cells still manage to maintain the
characteristics of life. Can you recall what the characteristics of life are? Prokaryotes are significantly smaller than
eukaryotes. In addition, prokaryotes exist only as single celled organisms (bacteria), while eukaryotes like amoebas,
mushrooms, mosses, trees, and humans can exist as either unicellular or multicellular organisms.
Even though bacteria are in the same kingdom, there is still much diversity. There are many different types of
bacteria and the way we categorize them depends on their shapes and the way they group together. There are 4 main
shapes that describe individual bacterial cells: coccus, bacillus, sprillum, and vibrio. The descriptions are shown in the
table below. Bacteria rarely exist by themselves as one cell, meaning they tend to form group togther in certain ways.
Some bacteria cells form pairs, while others cluster in large numbers. Some even link up in chains. Use the information
in the two tables below to answer the following sections.

Section 2: Answer the following questions based on what you have learned about bacteria.
a. Pneumonia is caused by a bacterium called pneumococcus, which are normally found in groups of two.
Which picture is likely to be pneumococcus? **
b. The bacteria that causes strep throat is a round bacteria that usually exists in a twisted chain. Which picture
might be representative of strep throat? **
c. Clostridium tetani, the bacterium that causes
tetanus is a bacillus. It looks like a bacillus
with a coccus attached to one end.
draw a picture of the bacteria in the box below.
d. Clostridium botulinum, the bacillus that causes
botulism (a type of food poisoning) is related
to the tetanus bacterium.
