Membrane
Bacteria are characterized by their shape and growth patterns. Spherical, round-
shaped bacteria are called ______.
Coccus
Bacteria are characterized by their shape and growth patterns. Spherical, round-
shaped bacteria are called coccus. When they grow in chains they are called
_______-coccus.
Strepto
,Bacteria are characterized by their shape and growth patterns. Spherical, round-
shaped bacteria are called coccus. When they grow in clusters they are called
________-coccus.
Staphylo
Bacteria are characterized by their shape and growth patterns. Rod shaped
bacteria are called ________, which means "rods."
bacillus
Bacteria are characterized by their shape and growth patterns. Spiral-shaped
(with rigid helices) bacteria are called ________.
Spirilla
Bacteria are characterized by their shape and growth patterns. Sphere shaped
bacteria are called _____.
Cocci
Some bacteria with flagella use the structure flagella to do __________, which is
the movement of a cell or organism in response to the chemical gradient.
Chemotaxis
These structures evolved to become embedded in the bacterium. It is within the
cell.
Endoflagella

made of ____________ called _______.
microtubules; tubulin
The flagella mechanism differs in prokaryotes and eukaryotes. Prokaryotic
flagella moves in a ________ motion.
rotating
The flagella mechanism differs in prokaryotes and eukaryotes. Eukaryotic flagella
moves by ______________________.
whipping from side to side
LABELING: This structure is made up of 1 DNA and many associated protein.
This molecule is circular and double stranded.
Chromosome
LABELING: This structure is small, circular DNA with 3-4 genes.
Plasmid
LABELING: This structure is smaller than its eukaryotic counter part. In
prokaryotes it is 70s and it is responsible for protein synthesis.
Ribosomes
LABELING: This structure stores molecules, such as chunks of phosphate and
starch.
Inclusion Body
LABELING: This term includes the various layers that surround the cell: plasma
membrane, cell wall, and capsule.
Cell Envelope
