
This is a bacterial cell.
Bacteria are single cell
organisms.
Bacteria are the oldest
organisms on the earth.
There is more bacteria in
mass and numbers than
all other life forms on the
planet.


All cells have
mitochondria.
Unlike all other
organelles (except the
chloroplast), they have a
double membrane.
We think they evolved
separately from cells and
were captured.
The Nucleus – the control center


The nucleus houses
the DNA that controls
all aspects of cell life.
The nucleolus makes
RNA, a messenger
for DNA’s
commands, which
goes to the ribosomes
to make proteins.

The plasma or cell
membrane is a double
layer.

Ribosomes – builders of proteins

http://www.google.com/
Ribosomes are found
free-floating and
attached to the
endoplasmic
reticulum.
They are the site
where amino acid
chains are assembled
to make proteins.
Plant cells


Plant cells have both
a cell wall and a cell
membrane.
The cell wall allows
plants to have great
water pressure to hold
the plant erect.
Vacuoles are used to
store nutrients.
