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

What’s a cell?
A CELL IS THE
SMALLEST UNIT
THAT IS CAPABLE OF
PERFORMING LIFE
FUNCTIONS.
Cell timeline
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.
Are they made of cells?
 people?
 cats?
 tomatoes?
 Mushrooms?
 Bacteria?
 The desk?
 Your pencil?
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
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.
Examples of Cells
Amoeba Proteus
Plant Stem
Bacteria
Red Blood Cell
Nerve Cell
Can you guess what the 5
groups of living things are?
You need: notebook, pen or pencil
No bell work…take a
chill…..come see me if
you missed the test…
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
organelles
“little organs”
Membrane (skin) bound
structures inside the cell.
 Different in each kind of cell
 All have different functions or jobs
Two Types of Cells
•Prokaryotes
Eukaryotes
 No organelles
 Have organelles
 No nucleus
 Have a nucleus
 Bacteria only
 All others (animals,
 Evolved first
plants, fungus and
protists)
 Evolved later
 More complex
 Small and simple
 Single celled
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!
How to set up organelle sheets

6.
7.
8.
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…
Animal cell organelles
1. Cell Membrane
8. Centrosome
2. Lysosome
9.Cytoplasm
3. nucleus
4. Nucleolus
10. Rough E.R.
(Endoplasmic Reticulum
11. Smooth ER
5. Nuclear Membrane
12. Ribosomes
6. Vacuole
13. Golgi Body
7. Mitochondria
Plant cell organelles
1. Cell Wall
2. Cell Membrane
3. Vacuole
4. Nucleus
5. Nucleolus
6. Nuclear Membrane
7. Chloroplast
8. Mitochondria
9. Cytoplasm
10. Rough ER
11. Smooth ER
12. Ribosomes
13. Golgi Body
(amyloplast/centrosome)
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
 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
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
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
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?
Worksheet:
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.
