Are bacteria prokaryotic or eukaryotic?
Prokaryotic
, due to them having
no nucleus
Name the organelles bacteria have
Cell wall
,
ribosomes
,
Plasmid DNA
, A
single loop
of of
chromosomal DNA
,
cell membrane
,
flagellum
What is plasmid DNA?
Contains
additional genes
that are not found in the
chromosomes
(eg,
antibiotic resistance
)
What is the single loop of DNA?
It is a single loop of
chromosomal DNA
that lies free in the
cytoplasm
, and contains most of the bacteria's
genes.
Why does the bacteria have a cell membrane for?
For
protection
, and it is not made out of
cellulose
What is a flagellum?
A
tail
to help the bacteria
move
Compare eukaryotic and prokaryotic cells
Eukaryotic:
-Contain a
nucleus
and
organelles
bound by
plasma membranes
-Nucleus
present
-Multicellular
Prokaryotic:
-Do not have a
membrane bound nucleus
or
organelles
-No nucleus
-Unicellular
What organelles do bacteria NOT possess that animal and plant cells do?
-No
mitochondria
-No
chloroplasts
-No
nucleus
