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
BELL WORKFIND HOOKE’S CELL THEORY
IN YOUR TEXTBOOK AND LIST THE 3 STATEMENTS
(ON PAGE 71)
Today you need:notebook, pen or pencil, textbook
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).
Cell Structure & Function
http://koning.ecsu.ctstateu.edu/cell/cell.html
A CELL IS THE SMALLEST UNIT THAT
IS CAPABLE OF PERFORMING LIFE
FUNCTIONS.
What’s a cell?
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 8Or 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 questionsThe questions with answers are on my calendar on the
date of the retest.
Examples of Cells
Amoeba Proteus
Plant Stem
Red Blood Cell
Nerve Cell
Bacteria
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 cellAll have different functions or jobs
•Prokaryotes•Prokaryotes EukaryotesEukaryotes
No organellesNo nucleusBacteria onlyEvolved firstSmall and simpleSingle celled
Have organellesHave a nucleusAll others (animals,
plants, fungus and protists)
Evolved laterMore complex
Two Types of Cells
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
1. Number the organelles on your plant and animal cell sheets as show on the overhead screen
2. Do not number amytoplast or centrosome on the plant cell –( draw a thin line through both of them)
3. Go to 2 fresh pages of your notebook (left and right)
4. Title the page “Animal Cell Organelles”
5. On the left, list 1-13 as shown on the next slide
6. Go to 2 more fresh pages and title them “Plant Cell Organelles”
7. List 1-13 as shown
8. Add the definitions as shown & we will practice…
Animal cell organelles1. 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
Plant cell organelles
1. Cell Wall 8. Mitochondria
2. Cell Membrane 9. Cytoplasm
3. Vacuole 10. Rough ER
4. Nucleus 11. Smooth ER
5. Nucleolus 12. Ribosomes
6. Nuclear Membrane 13. Golgi Body
7. Chloroplast (amyloplast/centrosome)
Function of plant organelles
1. hard cellulose (carb) outer layer2. wraps cell, controls in & out
3. stores water, food & waste
4.control center (holds DNA)5. center of nucleus6. wraps nucleus
7. Makes energy from sun by photosynthesis
8. Makes energy by cellular respiration9. holds organelles (jelly)10. E.R. with ribosomes11. E.R without ribosomes12. Makes proteins (cells) (from amino
acids) 13. Customizes proteins
Function of animal organelles
1. wraps cell, controls in & out2. digests (eats) waste3. control center (holds DNA)4. center of nucleus5. wraps nucleus6. stores water, food & waste7. 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 ribosomes11. ER without ribosomes12. makes proteins (cells) from amino
acids13. 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 paperUsing 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.
Cells bookwork Make a timeline using fig 1.3 on page 71 showing the contributions to cell theory

You need: Notebook, markers, 1 big white paper (if u
don’t have it from last time)
No bell work today
