6.12AB: Prokaryotic and Eukaryotic Cells
Organisms and Environments
1.  What is a cell?
2.  All living organisms are composed of how many cells?
3.  What cell organelles are in prokaryotic and eukaryotic cells?
4.  How is DNA stored within prokaryotic and eukaryotic cells?
5.  What are other similarities and differences between
prokaryotic and eukaryotic cells?

6.12AB: Prokaryotic and Eukaryotic Cells
Organisms and Environments
Robert Hooke was a well-known scientist who lived during the
1600s. He observed a piece of cork under a microscope and
noticed the arrangement of little boxes all in a row. He called
these boxes cells because they reminded him of the rooms that
monks would stay in.
Hooke started observing other things under the microscope
and soon discovered that all living things are made of cells.
Non-living things are not made of cells.

Bacterium
Bacterium
1.  Organisms made of only one cell
are called unicellular organisms.
2.  Bacteria are unicellular organisms.
3.  Bacteria you are familiar with
include Salmonella, E. coli, and
Streptococcus (strep throat).
Not all bacteria are bad, though.
Bacteria in your stomach and
intestines help with digesting of
food.

Plant Cells
Animal Blood Cells
1.  Organisms made of many cells are
called multicellular organisms.
Plants and animals are multicellular
organisms.
2.  Did you know that a person is made
of trillions of cells?
3.  Observe the pictures of the plant
cells and the animal blood cells.

Organisms and Environments
Instructions:
1.  Cells are so small that you
have to use a microscope
in order to see them.
2.  Using the microscope,
observe the piece of cork.

Organisms and Environments
1.  What does the cork look like?
2.  Is cork living or non-living?
3.  Is the cork unicellular or
multicellular?
1.  Read the
question and
think about the
answer.
2.  Turn to the
partner next to
you and share
your answers.
3.  After each
person has
spoken,
collaborate on
the best answer.
