 Third Time: Student can pick up the next day.
 Clean up after yourself.
 Put your books away when done.
 Tardy:
 If you have more than five tardies, it would be counted
as an absence.

Outcome for Term 1
Students are able to relate the
phenomena of a single cell to a life
of a single organism
Key terms

Can analyze the various theories of cell.

Can evaluate the difference between between prokaryotes and eukaryotes.

Can analyze process related to biology that happen in cell (DNA replication, RNA
Transcription, Protein Synthesis, Photosynthesis, Respiration, Cell Transport,
stages of Mitosis and Meiosis)

Can explain how cells interact with their extra-cellular environment to maintain their
internal environment within prescribed physiological limits

Can compare and contrast how do unicellular life and multicellular life maintain
homeostasis.

Can explain and describe through example on how multicellular life work together
to organize into tissue, organ, and organism.

Can determine controls of the development of cells and tissues in multicellular
organism.

Can create a concept about how the multicellular organism grow, based on how
cells grow and reproduce.

Weebly blog
 Weebly blog will be for daily journal. In the journal
you will write the following things after class:
 What did you learn today?
 Is there something that is still confusing you?
 Is there something that you don’t understand at
all?
 Write a question that you want answered
 It can be about Highscope
 About the class
 Or about the content
PRE-ASSESSMENT
 Please put everything away
 Take out a pencil or a pen
 Please don’t look at another student’s paper
 Please turn in the paper to me when you are done.
Cell Theory
 Robert Hooke:
 Almost all cells are too small to see
without the aid of a microscope.
 Finally in the late 1500’s the compound
microscope was invented, and it was
one of the early step towards discovery
Cell Theory 2
 In 1665 Robert Hooke used a three-lens
compound microscope to examine thin
slices of bark.
 Hooke saw tiny hollow
Compartments which looks
Like rooms in a monastery.
• Hooke gave them the name cells
Discoveries and
Assumptions
 If someone were to tell you that people once
believed that maggots came from rotting meat or
that rats came from damp roofs, you would quickly
write the person off as being very weird. However
this is what many people thought until 250 years
ago.
 These beliefs were based upon an idea called
“spontaneous generation.”
 WHY DO YOU THINK PEOPLE ACCEPTED THIS
ABSURD IDEA? HOW WAS THE IDEA FINALLY
PUT TO REST?
HOW CAN WE DISCOVER
MORE THINGS ABOUT
CELLS?
WHAT SHOULD WE DEVELOP, INVENT OR DO TO KNOW MORE ABOUT
CELLS OTHER THAN WHAT ROBERT HOOKE REPORTED?
The next discovery
 A textile worker used a more complex and powerful
lens than what Robert Hooke used and he was
discover more.
 WHAT DO YOU THINK HE WAS ABLE TO
DISCOVER ABOUT CELLS?
THE CELL THEORY:
HISTORICAL
PERSPECTIVE
•
PLEASE HAVE ONE OR TWO PEOPLE IN YOUR TABLE GET A
LAPTOP OUT.
• GET A BUTCHER PAPER FROM ME.
Questions 1
1. How did Janssen's, Hooke's, and Leewenhoek's
work contribute to the work of the scientists that came
after them?
2. How would our lives be different if we had never
realized the existance of microorganisms? Provide at
least one example to support your answer.
3. Describe the concept of spontaneous generation.
Why do you think it took such a long time for people to
accept that this idea was incorrect?
4. How do you think the cell theory impacted later
scientific discoveries? Explain your answer.
Questions 2
5. The microscope and numerous experiments lead to the rejection of
spontaneous generation. This idea had been accepted by most people,
including scientists, for over 200 years. How does this demonstrate the true
nature of science?
6. Review Pasteur's experiment. Relate his experiment to the scientific
method.
a. What was Pasteur's question?
b. State a reasonable hypothesis based upon this question.
c. What was the independent variable in Pasteur's experiment? What was
the dependent variable?
d. What did Pasteur conclude from his experiment?
7. Examine your timeline. How long did it take to develop the cell theory?
What does this imply about the formulation of a theory?
8. Why do we still consider the cell theory a theory? Explain your answer.
