3. Cell Facts
• Cells are microscopic - too small to be
seen without a microscope.
• Humans are made of about 90 trillion cells.
• If a single cell can live on its own, it is
called a unicellular organism.
• Humans are multicellular organisms.
Bacteria are unicellular.

5. Organization of Life
• Organisms - living creatures. Any life form that
survives on its own.
• Organ systems - made up of organs - work together
to make an organism function. Example: digestive
system
• Organs - made up of tissues - work together to
make organ systems function. Example: stomach
made of muscle tissue and skin tissue

6. • Tissues - made up of cells - work together to
make organs function. Example: skin tissue
made up of different kinds of skin cells.
• Cells – made up of organelles. Cells work
together to make tissues.
• Organelles – structures inside cells that do the
cell’s work.
Organization of Life continued…

7. 1. Every living thing is made up of one or more
cells.
• 2. The cell is the smallest, most basic unit of
life in all living things.
• 3. All cells come from existing cells.

The Cell Theory

8. Prokaryotic Cells
– Don’t have a nucleus.
– Another name for
them is bacteria.
– They are ONLY
unicellular – never
multicellular
Yes, draw this and label it

9. • Congratulations! You have reached the end of
Cell Notes #1. Don’t forget to do the reflection
activity your teacher assigned on the left hand
page (clock question, one pager, learning log
question, etc..)
• The next slide will start Cell Notes #2. Enjoy!

11. Eukaryotic Cells
• DO have a nucleus
• belong to multicellular
organisms
• There are some
unicellular eukaryotes
(amoeba, euglena,
paramecium)
Click here to watch a video of how to
draw this...
Yes, draw this!

12. Eukaryotic Cells continued…
• Eukaryotes:
– have membrane-
covered organelles.
– Their DNA is linear
(organized in lines)
– They’re 100 x bigger
than prokaryotes.
Example of prokaryote (bacteria) in size
comparison to eukaryote cells (human skin
cells). Human cell is circled in green,
bacteria cell is circled in red. Image via
Biophilia.
No, don’t draw this.

13. Prokaryotic vs. Eukaryotic
No Nucleus Nucleus
No Membrane – covered
Organelles
Membrane – covered
Organelles
Circular DNA (in a circle) Linear DNA (in a line)

eukaryotes
All other cells
100 x bigger than
prokaryotes

14. No, you
don’t need
to draw
these...

15. No – don’t draw these... Just check out the differences between them.

16. ANIMAL CELL No, don’t draw this - you already
drew an animal cell.

17. PLANT CELL Yes, draw this!

18. CELL MEMBRANE
• Keeps good stuff in (nutrients, water), and bad stuff out (waste,
toxins, viruses, bacteria).
• Made from lipids (phospholipid bilayer)
no, you
don’t
have to
draw
this
picture

19. Cell Membrane
Honors students only – draw this

20. Cell Wall
• Hard Wall made of
cellulose fibers. Rigid &
Stiff. Provides strength &
support to cell. Cell walls
are only in plant and
bacteria cells.
• Holes called
plasmodesmata, allow
transfer of nutrients,
waste, and water.
All
students:
draw this
Honors
students:
draw this
one too.

21. • Congratulations! You have reached the end of
Cell Notes #2. Don’t forget to do the reflection
activity your teacher assigned on the left hand
page (clock question, one pager, learning log
question, etc..)

23. • Is the control center of the cell. Stores
information (DNA) on how to run the cell and
build new structures.
• Largest organelle in the cell
• Inside the nucleus is the nucleolus – it stores
ribosome parts
No, don’t copy this picture
NUCLEUS
Nucleus

24. • Ribosomes are machines that read RNA strands and
assemble amino acids into long chains that fold into
protein molecules.
• Proteins are the building blocks for all structures
built in the cell.
• Ribosomes are also called“Protein Factories”
No, don’t copy this picture
Yes, copy this picture

25. Ribosomes
• Honors students only – draw and label!

26. Chaperones
• Machines that help newly constructed proteins to fold correctly.
• Mad cow disease & Alzheimer's disease are caused by
mis-folded protein molecules.
Chaperones
No, don’t copy this picture

27. • Stores water, minerals & other fluids.
• Only found in plant cells – animal cells have tiny ones.
Central
Vacuole
Don’t draw
this – you
already
drew a
central
vacuole in
cell notes
#1

28. Central Vacuole
Honors students only – draw this

29. No, don’t copy this picture Yes, draw this picture
One mitochondrion
• The mitochondria
– Are the powerhouses of the cell – contain over 300,000
rotating machines called ATP synthases.
– They use oxygen and food (glucose) to make ATP energy
• ATP = energy molecules (Adenosine triphosphate)

30. ATP SYNTHASE
No,
you
don’t
have
to
draw
this.

31. ATP SYNTHASE – hundreds of these machines in each mitochondrion CLICK FOR LINK
CLICK FOR A short
VIDEO – It’s cool –
I promise!

32. ENDOPLASMIC RETICULUM
• Smooth E.R. breaks down toxins, and makes lipids which
are used for membranes. Doesn’t have ribosomes.
• Rough E.R. DOES have ribosomes, and like an assembly line
in a factory, it builds, packages, & transports proteins.
No, don’t copy this picture, but copy this one!

33. Rough E.R. (endoplasmic reticulum)

34. Model of how proteins are made and shipped out of the cell.

A vesicle can
carry any kind of
cargo: food,
waste, protein
molecules...
Vesicles
Kinesin walker
(motor protein)

42. Cytoskeleton
• The cytoskeleton is a network of microtubules
– it gives shape to the cell & transportation for
kinesin walkers – they walk on the
microtubules and pull vesicles.

foreign invaders.
Lysosome

44. PEROXISOME
