There are two main types of cells: prokaryotic and eukaryotic. Prokaryotic cells lack a nucleus and membrane-bound organelles, have circular DNA, and examples include bacteria. Eukaryotic cells have a nucleus and membrane-bound organelles like mitochondria and chloroplasts, have linear DNA, and examples include plant, animal, fungus and protist cells. While prokaryotic cells were likely the first to exist on Earth, eukaryotic cells are larger and more complex with internal structures that allow them to perform specialized functions in multicellular organisms.

1. Types of Cells
Objective:
You will be able to explain the differences
between the 2 types of cells.

3. Prokaryotic Cells
1. No nucleus
2. No membrane covered
organelles
3. Circular DNA
4. Examples: Bacteria!
Draw picture!!!!
Eukaryotic Cells

4. Prokaryotic Cells
Did you know?
Prokaryotic cells were
probably the first type of
cells to exist on Earth and
are commonly found in the
oldest fossils ever found.

5. Prokaryotic Cells
Eukaryotic Cells
1. No nucleus
1. Nucleus
2. No membrane covered
organelles
2. Membrane covered
organelles
3. Circular DNA
3. Linear DNA (line)
4. Examples: Bacteria!
Draw picture!!!!
4. Examples: Every other
type of cell: animal, plant
fungus, protist

6. Eukaryotic Cells
Did you know….
Eukaryotic cells are
more complex and are
larger. This type of cell
has a nucleus and
many organelles inside.
This allows the cell to
perform many different
jobs in multicellular
organisms!

8. • Neurons, or nerve
cells are the longest
cells in the human
body. They can be
more than 1meter
long!

9. • Red blood cells do
not have a nucleus.
They are produced in
the "flat" bones of the
body, live for about
120 days, and die
without reproducing.
Their sole purpose is
to carry oxygen and
carbon dioxide in the
blood.
The END!!!
