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.
AFTER THE TEST: ANSWER USING
YOUR TEXTBOOK
1. LIST THE 3 PRINCIPLES OF CELL
THEORY
2. COPY THE NAMES OF THE 5
SCIENTISTS ON PAGE 71 – HOW
DID EACH CONTRIBUTE?
Today you need:
pen or pencil, notebook, textbook
TEST TODAY!! study for 10 minutes
BELL WORK-
NO BELL WORK…..
Today you need: notebook,
pen or pencil, 1 big white
paper, markers/ruler to share
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?
Examples of Cells
Amoeba Proteus
Plant Stem
Red Blood Cell
Nerve Cell
Bacteria
1.
Can you guess what the 5
groups of living things are?
organelles
“little organs”
Membrane (skin) bound
structures inside the cell.
Different in each kind of cell
All have different functions or jobs
Today you need: notebook, pen or
pencil, markers to share
Bell work:
Copy:
Cyto=cell, endo=within,
iso=equal,
hypo=below, kary=kernel,
exo=out of, hyper=above
Progress Reports
Return signed if you are failing
The last test was curved (plus 30 points up
to 100)
Retests will be next Thursday/Friday @8.
(I will give you a copy of the questions in
advance if you plan on taking it)
You can redo your enzyme for more credit.
Parent night Thursday….
•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
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!
Animal cell organelles1. Cell Membrane 8. ribosomes
2. x 9. Rough E.R.(Endoplasmic Reticulum)
3. nucleus 10. centrioles
4. Nucleolus 11. Mitochondria
5. Vacuole 12. Golgi body
6. cytoplasm 13. Smooth E. R.
7. Nuclear membrane 14. Lysosome
Organelle functions:
Fold your paper in ½
twice lengthwise
Copy the following:
organelle functions.xlsx
Today you need: one white paper,
markers to share, ruler, notebook, pen or
pencil
Bellwork:
No bell work
Worksheet:
Using your foldables & your
textbook to complete the following
worksheet..
Do these exist in plants, animals or
both? X for yes
Now answer the 4 questions at the
bottom.
Open your hard book to R8/9
1. Draw and label the microscope parts in the pic on R8
2.. write an abbreviated version on the instructions on
“viewing an object”
3.. write an abbreviated version of how to do a wet mount
from page R9
4.. Just read over “staining a specimen” – I will show you
a slightly different process.
You will need to reference your notes to pass the
Microscope Lab which counts as a test grade
