1. Pick up handout from back
2. Pick up for you and table partner glue or tape and
scissors.
3. Turn in your enzyme lab packet from last time.
4. Take out your notebook.
5. Find a free left and right page in notebook.
6. On the RIGHT side, title your notes “Cell Size”.
7. On the LEFT side of your notebook title it “What
I know about cells” (Need help? Find the notes
we already took on cells)
1. Now identify as many things as you know about cells
as today’s bell work.
Type pd. 4 responses here.
What Ms. Henriques said you should
already know about cells.
• The definition – “Cells are the basic unit of
structure & function. They are the building blocks
of ALL life”.
• The two types
1. Prokaryotic cells. These cells do not have
compartments, a nucleus nor do they have membrane
bound organelles.
• Only bacteria are prokaryotes
• All prokaryotes are unicellular
What you should know continued
1. Eukaryotic cells - These cells HAVE
compartments, a nucleus AND they have
membrane bound organelles.
• All eukaryotes can be unicellular or multicellular.
• They have organelles such as chloroplast, rough ER,
smooth ER, glogi apparatus, etc.
• They are 2 types of eukaryotic cells.

Prokaryote? Or Eukaryote?
• How do you know?
• It is a prokaryotic
cell because it
doesn’t have
compartments, a
nucleus, nor does it
have membrane
bound organelles.
Prokaryote? Or Eukaryote?
• How do you know?
• It is a eukaryotic cell
because it HAS
compartments,
nucleus AND it HAS
membrane bound
organelles.

2 types of eukaryotic cells
• All eukaryotic cells have a nucleus and
membrane bound organelles.
• A plant cell is a type of eukaryotic cell.
• An animal cell is the 2nd type of eukaryotic
cell.
How can you tell if it’s a
Plant or Animal?
• It is a eukaryotic
plant cell because
it HAS:
– Vacuole
– Chloroplast
– Cell wall
• Animal cells DO
NOT HAVE those
organelles.
How can you
tell if it’s a
Plant or Animal?
Centrioles lysosome
lysosome
• How do you know?
• It is a eukaryotic
animal cell because it
DOES NOT HAVE
– Vacuole
– Chloroplast
– Cell wall
• But it DOES HAVE
– Lysosome
– centrioles

Cell
• The cell is the building
blocks of life.
• According to the
hierarchy, cells couldn’t
exists without the levels
before it.
• A cell cannot function
without all its organelles
working properly.
• Let’s talk about
organelles.
