WARM UP TASK 11/27
Read each statement on your
“Intro to Cells video sheet” and
put a T or F on the LEFT SIDE
ONLY.
(you are making your best guess)
AGENDA 11/27
1. Ch 4 Notes #1 Intro to cells
2. Intro to cells video
3. Do you know your own cells?
* Can get EC from this!
*** MISSING TESTS – TAKE
TOMORROW!!!!
LEARNING TARGET
CHAPTER 4
#1
I can explain the major events in
cell history.
Ch 4 NOTES #1
11/27
THE CELL intro
3.6 billion years ago – 1st
cells
PROKARYOTE - bacteria
No nucleus

&sns=em
1.3 billion years ago
EUKARYOTE CELLS – do have
nucleus ; also organelles
Over time ….
Cells became specialized –
different cells do different things
Brain cell Blood cell Skin cell….
and grouped together to become
multicellular.
TAKE YOUR INTRO TO CELLS
VIDEO SHEET OUT
CELL VIDEO – while watching,
write down if the statement is T
or F.
See how many you got right!
1668 VanLeeuwenhoek
Developed the 1st microscope
1670’s HOOKE
1st saw cells
(cork) AND
named CELLS
Cellula = small
compartment
1838 SCHLEIDEN AND
SCHWANN
All living things
are made of
cells
1858 VIRCHOW
All cells come
from cells
REVIEW…..
1. What came first, eukaryote or
prokaryote?
2. EXPLAIN how one evolved into the
other.
3. Name 4 people who contributed in
the history of cells.
* What did they do?
CELL THEORY
1. All living things made of cells.
2. Cells are the basic unit of all
living things.
3. All cells come from preexisting cells
(exception: first cell ?????)
CELLS – the basic unit of all living
things
CYTOLOGY
The study of cells
About 75 trillion in
the human body!
Around 200
different types
Many different
shapes, sizes
and functions
Smallest cell:
1/12,000 inch
blood cell
Largest cell:
1/300 inch
female egg
Longest cell:
around 3 feet
nerve cells
Journey into our cells

TO DO
Make sure you turned in your
notes packet from Chapter 3
Check folder for any missing work
– can throw away old papers in
your folder that you wont need
SAVE ALL OLD NOTES, STUDY
GUIDES, and TESTS!!!!
ORGANELLES
tiny parts of the cell
Each organelle has a specific
function
CELL MODEL LABELING
Have out your cell sheet
Animal and plant cell
Label the parts

fill in your chart
ASSIGNMENT
Before 1660’s –
SPONTANEOUS
GENERATION
THEORY
“living things
come from nonliving things”
Kill a young bull, and bury it in an upright position so
that its horns protrude from the ground. After a month,
a swarm of bees will fly out of the corpse.
Place a dirty shirt or some rags in an open pot or barrel
containing a few grains of wheat or some wheat bran,
and in 21 days, mice will appear.
CELL EVOLUTION
VIDEO
• From simple
one celled
prokaryotic
to
complex
multicellular
eukaryotic
• Theory is a well established
explanation based on extensive
experimentation and
observation.
• Scientific theories are
developed and verified by the
scientific community and are
generally accepted as fact.
