Two “Classes” of CellsTwo “Classes” of CellsThere 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 show.them by the end of the show.

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.

CytoplasmCytoplasm

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

Cytoplasm is like the turtle’s blood and Cytoplasm is like the turtle’s blood and other liquids in which the organs bathe.other liquids in which the organs bathe.

MitochondriaMitochondria

Mitochondria is an ORGANelle that Mitochondria is an ORGANelle that breaks down food to make energy.breaks down food to make energy.

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

NucleusNucleus

The nucleus controls the cell.The nucleus controls the cell.The nucleus is like the turtle’s brain.The nucleus is like the turtle’s brain.

NucleolusNucleolus

The nucleolus can be found inside the The nucleolus can be found inside the nucleus.nucleus.

It makes ribosomes for the cell.It makes ribosomes for the cell.

Chromosomes Chromosomes (Chromatin)(Chromatin)

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 rate, eye activities (heart rate, eye color, tongue rolling).color, tongue rolling).

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 nucleus.nucleus.

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

Endoplasmic reticulumEndoplasmic reticulumThe endoplasmic reticulum is the The endoplasmic reticulum is the

“highway” of the cell.“highway” of the cell. It moves substances throughout the It moves substances throughout the

cell like the blood vessels in a turtle cell like the blood vessels in a turtle move blood and nutrients throughout move blood and nutrients throughout its body.its body.

Did someone say blood?

RibosomesRibosomes

The ribosomes make proteins for the cell.The ribosomes make proteins for the cell.Think of the turtles “ribs” which are Think of the turtles “ribs” which are

covered with yummy protein-filled meat.covered with yummy protein-filled meat.Ribosomes can be found on the Ribosomes can be found on the RROUGH OUGH

endoplasmic reticulum.endoplasmic reticulum.

Turtle soup?

Golgi body or Golgi Golgi body or Golgi apparatusapparatus

The golgi body is the “post office” for the cell.The golgi body is the “post office” for the cell. It packages substances for movement out of It packages substances for movement out of

the cell.the cell.

VacuolesVacuolesVacuoles are compartments in the Vacuoles are compartments in the

cytoplasm where food and chemicals cytoplasm where food and chemicals are stored.are stored.

In animal cells, lysosomes are vacuoles In animal cells, lysosomes are vacuoles that break down substances for the cell.that break down substances for the cell.

Just call me“Count

Vacula”!

Cell WallCell WallCell Walls are only in plant cells.Cell Walls are only in plant cells.They make the cell strong and rigid.They make the cell strong and rigid.They 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!)

Plant vacuolePlant vacuole

The plant vacuole is also called the The plant vacuole is also called the water vacuole because it stores water water vacuole because it stores water for the plant.for the plant.

It’s like the turtle’s own private pool.It’s like the turtle’s own private pool.

Chloroplasts Chloroplasts Chloroplasts are Chloroplasts are onlyonly in plant cells. in plant cells.They contain chlorophyll, which is a They contain chlorophyll, which is a

pigment that captures sunlight so pigment that captures sunlight so that food can be made.that food can be made.

Chlorophyll is green in color…so any Chlorophyll is green in color…so any plant that is green has chloroplasts.plant that is green has chloroplasts.

I’m green…do I have

chloroplasts?

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

So what are So what are THREETHREE things that plant things that plant cells have that animal cells don’t?cells have that animal cells don’t?

?Chloroplasts, Cell Walls & a Water Vacuole

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