Warm-up
Do you know the cell part?
Take out a sheet of paper. You
have 5 minutes to get as many
right as you can.
Lesson Title: Plant and Animal
Cells
E.Q.: How can you distinguish between
plant and animal cells?
 Obj.: Compare and contrast plant and
animal cells; Create a wet-mount slide;
Properly stain a specimen.


Cells

Cells are the basic unit of all living
things…if it is alive it has cells
Two “Classes” of Cells

There are 2 classes of cells. There are
only two differences between Plant &
Animal cells…try to spot them by the end
of the show
Plant cells
Animal Cells
Cell Differentiation

There are only 2 classes of cells
(plant/animal), but there are many kinds
of cells in each class. Each kind of cell has
a DIFFERENT job to do…it specializes.
I am a
heart cell!
I am a
skin cell
I’m a
Prison
Cell! 
When you hear the new
vocabulary…just think of a
Turtle
 The
Cell Membrane
cell membrane holds the cell
together and allows nutrients in the cell
 It’s just like a turtle’s skin
 The cell membrane is on the edge of a
cell
Cytoplasm
Cytoplasm is the watery gel (Jello!) inside
a cell….it’s goop! It holds the ORGANelles
 Cytoplasm is like the turtles blood and
other liquids

Mitochondria
Mitochondria is an ORGANelle that
releases energy from food
 Mitochondria is like a turtle’s stomach

Nucleus
The nucleus controls the cell
 The nucleus is like the turtle’s brain

Chromosomes
Chromosomes are inside the nucleus and
are made of genes (DNA)
 Genes decide the cells traits and activities
(heart cell, eye cell (color))

Nuclear Membrane
The nuclear membrane allows substances
to pass in and out of the nucleus
 It surrounds the nucleus (the brain) like
the turtle’s skull…protects it

Vacuoles
Vacuoles are spaces in the cytoplasm (gel)
where food and chemicals are stored
 It’s like “fat” on a turtle

I am NOT
fat…I’m just a
little plump!!
Cell Wall
Cell Walls are only in plant cells
 They make the cell strong and rigid
 They are like a turtle’s shell (but only
plants have them…that’s why grass stands
straight up!)

Chloroplasts
Chloroplasts are only in plant cells
 They contain chlorophyll, which helps
make energy/food from sunlight
 Chlorophyll is green in color…so any plant
that is green has chloroplasts

I’m green…do I
have
chloroplasts?
What’s the Difference?

So what are two things that Plant cells
have that animal cells don’t?
?
Chloroplasts &
Cell Walls
What would happen if animals had
Chloroplasts?
Now, let’s review…
Cell Membrane
 Chromosomes
 Mitochondria
 Plant/Animal

Cell Wall
Chloroplasts
Nucleus Nuclear Membrane
Cytoplasm
Vacuoles
Cell Differentiation
Cells
Congratulations

You now know all the vocabulary for cells
