Cells are the basic unit of all living Cells are the basic unit of all living things…if it is alive it has cellsthings…if it is alive it has cells

Two “Classes” of CellsTwo “Classes” of Cells

There are 2 classes of cells. There There are 2 classes of cells. There are only two differences between are only two differences between Plant & Animal cells…try to spot Plant & Animal cells…try to spot them by the end of the showthem by the end of the show

Plant cells Animal Cells

Cell DifferentiationCell DifferentiationThere are only 2 classes of cells There are only 2 classes of cells

(plant/animal), but there are many (plant/animal), but there are many kinds of cells in each class. Each kinds of cells in each class. Each kind of cell has a DIFFERENT job to kind of cell has a DIFFERENT job to do…it specializes.do…it specializes.I am a

heart cell! I am a skin cell

I’m a Prison Cell!

When you hear the new When you hear the new vocabulary…just think vocabulary…just think

Turtle

Cell MembraneCell MembraneThe cell membrane holds the cell The cell membrane holds the cell

together and allows nutrients in the celltogether and allows nutrients in the cellIt’s just like a turtle’s skinIt’s just like a turtle’s skinThe cell membrane is on the edge of a The cell membrane is on the edge of a

CytoplasmCytoplasm

Cytoplasm is the watery gel (Jello!) Cytoplasm is the watery gel (Jello!) inside a cell….it’s goop! It holds the inside a cell….it’s goop! It holds the ORGANellesORGANelles

Cytoplasm is like the turtles blood and Cytoplasm is like the turtles blood and other liquidsother liquids

MitochondriaMitochondria

Mitochondria is an ORGANelle that Mitochondria is an ORGANelle that releases energy from foodreleases energy from food

Mitochondria is like a turtle’s stomachMitochondria is like a turtle’s stomach

NucleusNucleus

The nucleus controls the cellThe nucleus controls the cellThe nucleus is like the turtle’s brainThe nucleus is like the turtle’s brain

ChromosomesChromosomes

Chromosomes are inside the nucleus Chromosomes are inside the nucleus and are made of genes (DNA)and are made of genes (DNA)

Genes decide the cells traits and Genes decide the cells traits and activities (heart cell, eye cell (color)) activities (heart cell, eye cell (color))

Nuclear MembraneNuclear Membrane

The nuclear membrane allows The nuclear membrane allows substances to pass in and out of the substances to pass in and out of the nucleusnucleus

It surrounds the nucleus (the brain) It surrounds the nucleus (the brain) like the turtle’s skull…protects itlike the turtle’s skull…protects it

VacuolesVacuoles

Vacuoles are spaces in the cytoplasm (gel) Vacuoles are spaces in the cytoplasm (gel) where food and chemicals are storedwhere food and chemicals are stored

It’s like “fat” on a turtleIt’s like “fat” on a turtle

I am NOT fat…I’m just

a little plump!!

Cell WallCell Wall

Cell Walls are only in plant cellsCell Walls are only in plant cellsThey make the cell strong and rigidThey make the cell strong and rigidThey are like a turtle’s shell (but only They are like a turtle’s shell (but only

plants have them…that’s why grass plants have them…that’s why grass stands straight up!)stands straight up!)

Chloroplasts Chloroplasts

Chloroplasts are only in plant cellsChloroplasts are only in plant cellsThey contain chlorophyll, which helps They contain chlorophyll, which helps

make energy/food from sunlightmake energy/food from sunlightChlorophyll is green in color…so any Chlorophyll is green in color…so any

plant that is green has chloroplastsplant that is green has chloroplasts

I’m green…do I have

chloroplasts?

What’s the Difference?What’s the Difference?

So what are two things that Plant So what are two things that Plant cells have that animal cells don’t?cells have that animal cells don’t?

?

Chloroplasts & Cell Walls

What would happen if animals What would happen if animals had Chloroplasts?had Chloroplasts?

Now, let’s review… Now, let’s review…
