Do you know the cell part? November 8 and 9, 2007 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’m a Prison Cell! I am a skin cell
When you hear the new vocabulary…just think of a Turtle
Cell Membrane The 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
I am NOT fat…I’m just a little plump!! 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!)
I’m green…do I have 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?
Chloroplasts & Cell Walls 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 Cell Wall Chloroplasts Chromosomes Nucleus Nuclear Membrane Mitochondria Cytoplasm Vacuoles Plant/Animal Cell Differentiation Cells
Congratulations You now know all the vocabulary for cells
