There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells do not have a nucleus and are generally smaller, while eukaryotic cells do have a nucleus and are larger with many specialized organelles. The key difference between the two cell types is whether or not they contain a nucleus.

1. CELLS COME IN ALL SHAPES AND
SIZES!

2. THERE ARE TWO TYPES OF CELLS:
Prokaryotic Cells
and
Eukaryotic Cells

3. Prokaryotes
Bacteria
Eukaryotes
Animal Plant
THESE ARE TWO DISTINCT TYPES OF
CELLS WITH STRUCTURAL
DIFFERENCES.

5. PROKARYOTE CELL
A single celled
organism that
does not have a
nucleus.

6. TRAITS OF PROKARYOTES:
 They do not have a nucleus, and their genetic material is
not stored in the nucleus.
 They have some organelles, but not many.
 They are small ,size ranging from 1 to 10 µm.
 All bacteria and blue- green algae
 They have a rigid cell wall containing polysaccharide murein
 Flagella if present lack microtubules.

7. EUKARYOTE CELL
A more complex
cell with a
nucleus and many
organelles.

8. TRAITS OF EUKARYOTES:
• They all have a distinct nucleus where the genetic material
of the cell is stored.
• They have many organelles that work together to help the
cell function.
• They are large usually between 10 and 100 µm.
• Cell wall is found in plants and fungi .
• Flagella have microtubules
• Examples : plants , animals,fungi and protoctists

11. What do you think is
the main
difference between
a prokaryotic cell
and a eukaryotic
cell?

12. The nucleus!
Prokaryotic cells do not
have a nucleus and
eukaryotic cells do have a
nucleus. This allows
eukaryotic cells to make
multi-cellular organisms
and perform more complex
functions.
