1. 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.

2. 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.

3. Agenda Warm-up-Cell Analogy (Bells 4 and 6)
“Like a Turtle”-Review cell parts and functions
Quiz-Cell history and cell parts/functions
Quiz-Weekly notebook quiz
Pre-lab discussion and questions (p. 28 in IT)
Lab-Comparing plant and animal cells (p. 28 in IT)
Homework-p. 181, 1-5 (p. 25 in interactive notebook)

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

6. 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

7. 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

8. When you hear the new vocabulary…just think of a
Turtle

9. 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

10. 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

11. Mitochondria
Mitochondria is an ORGANelle that releases energy from food
Mitochondria is like a turtle’s stomach

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

13. Chromosomes
Chromosomes are inside the nucleus and are made of genes (DNA)
Genes decide the cells traits and activities (heart cell, eye cell (color))

14. 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

15. 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!!

16. 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!)

17. 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?

18. Chloroplasts & Cell Walls
What’s the Difference?
So what are two things that Plant cells have that animal cells don’t? ?
Chloroplasts & Cell Walls

19. What would happen if animals had Chloroplasts?

20. Now, let’s review… Cell Membrane Cell Wall Chloroplasts
Chromosomes Nucleus Nuclear Membrane
Mitochondria Cytoplasm Vacuoles
Plant/Animal Cell Differentiation Cells

21. Congratulations
You now know all the vocabulary for cells
