1. Objectives Students will discuss the development of cell theory.
Students will be able to discriminate between living and non-living things.
Students will draw and animal and plant cell and label it’s parts.
Students will make a foldable of the organelles of both and practice naming them on an unmarked poster.
Students will practice explaining the function of these organelles.

2. Study for the test for a while….
After the test…
Turn your test and answer sheet in to me…
I will have bell work on the screen..
You will need:
Your notebook, a textbook and something to write with

3. Today you need: notebook, pen or pencil, textbook
BELL WORK
Find Hooke’s Cell theory in your textbook and list the 3 statements
(on page 71)

4. Parent s that do not work: Please stop by the front office and give them a valid for your parents (if they have one).

5. Cell Structure & Function

6. What’s a cell?
A cell is the smallest unit that is capable of performing life functions.

7. Cell timeline

8. Hooke’s - Cell Theory All living things are made up of cells.
Cells are the smallest working units of all living things.
All cells come from preexisting cells through cell division.

9. people? cats? tomatoes? Mushrooms? Bacteria? The desk? Your pencil?
Are they made of cells?
people?
cats?
tomatoes?
Mushrooms?
Bacteria?
The desk?
Your pencil?

10. Today you need: colors to share, 3 big white papers, 1 tiny white paper, pencil
Bell work:
Study your notes on the difference between prokaryotes and eukaryotes…we will be having a quiz on it today

11. Test grades Retests: Offered Monday the 22nd at 8
Or during your lunch (bring something to eat)
You will need a pass to get up the hall. (In front)
You can retake it regardless of your grade (passing or failing)
The test is 4 essay questions
The questions with answers are on my calendar on the date of the retest.

12. Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell
Nerve Cell

13. Can you guess what the 5 groups of living things are?

14. You need: notebook, pen or pencil
No bell work…take a chill…..come see me if you missed the test…

15. Cells have an internal structure.
The cytoskeleton has many functions.
supports and shapes cell
helps position and transport organelles
provides strength
assists in cell division
aids in cell movement

16. Membrane (skin) bound structures inside the cell.
organelles
“little organs”
Membrane (skin) bound structures inside the cell.
Different in each kind of cell
All have different functions or jobs

17. Two Types of Cells Prokaryotes Eukaryotes No organelles No nucleus
Bacteria only
Evolved first
Small and simple
Single celled
Have organelles
Have a nucleus
All others (animals, plants, fungus and protists)
Evolved later
More complex

18. Let’s draw some cells…. We are going to draw a colored plant and animal cell, label all the organelles and learn what each of them do!

22. How to set up organelle sheets
Number the organelles on your plant and animal cell sheets as show on the overhead screen
Do not number amytoplast or centrosome on the plant cell –( draw a thin line through both of them)
Go to 2 fresh pages of your notebook (left and right)
Title the page “Animal Cell Organelles”
On the left, list 1-13 as shown on the next slide
Go to 2 more fresh pages and title them “Plant Cell Organelles”
List 1-13 as shown
Add the definitions as shown & we will practice…

23. Animal cell organelles
1. Cell Membrane
8. Centrosome
2. Lysosome
9.Cytoplasm
3. nucleus
10. Rough E.R.
(Endoplasmic Reticulum
4. Nucleolus
11. Smooth ER
5. Nuclear Membrane
12. Ribosomes
6. Vacuole
13. Golgi Body
7. Mitochondria

24. Plant cell organelles 1. Cell Wall 8. Mitochondria 2. Cell Membrane

10. Rough ER
4. Nucleus
11. Smooth ER
5. Nucleolus
12. Ribosomes
6. Nuclear Membrane
13. Golgi Body
7. Chloroplast
(amyloplast/centrosome)

25. Function of plant organelles
1. hard cellulose (carb) outer layer
2. wraps cell, controls in & out
3. stores water, food & waste
4.control center (holds DNA)
5. center of nucleus
6. wraps nucleus

26. 7. Makes energy from sun by photosynthesis
8. Makes energy by cellular respiration
9. holds organelles (jelly)
10. E.R. with ribosomes
11. E.R without ribosomes
12. Makes proteins (cells) (from amino acids)
13. Customizes proteins

27. Function of animal organelles
1. wraps cell, controls in & out
2. digests (eats) waste
3. control center (holds DNA)
4. center of nucleus
5. wraps nucleus
6. stores water, food & waste
7. makes energy by cellular respiration

28. Function of animal organelles
8. pulls genetic material apart in cell division
9. holds organelles (jelly)
10. E.R. with ribosomes
11. ER without ribosomes
12. makes proteins (cells) from amino acids
13. customizes proteins

29. Bacteria
We are not learning the parts…
Let’s look at the differences…be ready to identify a bacteria when you see one.
Is it a prokaryote or eukaryote?
How can you tell by looking at this drawing?

30. copy the worksheet onto your paper
Using your notes to complete the top of the worksheet
Do these exist in plants, animals or both? X for yes
Now answer the 4 questions at the bottom.
