Transcript of Copy of Cell Theory & Level of Organization

Cell- basic unit of life;
Specialized based on function
Organelle- part of a cell with a special function
Tissue- Group of Cells
with similar function
Organ- Group of tissues working with a similar function
Organ system- group of organs with similar task
Cell discovered by Robert Hooke
Hooke looked at cork under a microscope
and noticed tiny pores. Called them "cells" named after a monk's living area.
Cell Theory
1) All living organisms are made of 1 or more cells
2) Cells are the basic unit of life
3) New cells are created by old
cells dividing in two
Eukaryotic Cells
"=True; "
Animals, plants, fungi
Mostly multi-cellular
1) Add to your Table of Contents:
Page 28. Levels of Organization
Page 29. Cell Theory
Get your Science binders,
folders & notes.

On a blank piece of paper, write the question and answer...
-What is a group of cells with similar function called?
-Write the levels of organization
in order.
Flipped Training
1) Upload a video to your iPad while in class
2) Watch video at home and take notes during it
in your Science notebook (yes, notes at home!)
3) In class, listen to discussions and add to notes as needed
2) Draw Cornell Notes on page 29
3) Exchange notebooks
Notebook Grade
Add 1 point for each page that contains notes or graphics on pages 24,25,26,27

Write total score on Week 3 of Interactive Score Sheet on page 4
Capable of responding to stimuli, reproduction, growth, homeostasis
Levels of Organization
Organ System
Move Reproduce
Breathe Speak
Grow Remove Waste
Label Pg. 52 "Cell Theory Notes"
At the top of Pg. 51, write from this list what you think makes something "alive."
Think about it, don't just guess!
He did not know anything about their structure or function though.
First to view a live cell under a microscope was Antonie van Leeuwenhoek.
Called these moving organisms "animalcules," meaning little animals.
Credited to several scientists
(Schwann, Schleiden, Virchow)
"Cell Theory" Article
1) Number Paragraphs

2) Important words & ideas

3) Words you don't know

4) Summarize! Facts only, 4-5 sentences.
When done with your number group, return to your home table. Answer on the butcher paper...
1) Define "cell" in your own words from the article.
2) List 3 things you think are part of the "Cell Theory."
3) Why does your group think these discoveries are important?
"At what moment are you dead" Video
During the video, watch for the importance of cells in life and death. We will discuss this after the video.
In seat, Voice level 0
Summary & Questions
In journal on bottom half of Pg. 50, write a 4-5 sentence summary and answer...
1) What object did Robert Hooke observe under a microscope?
2) What did Leeuwenhoek see under a microscope? what did he call them?
3) What scientist looked at plant cells? Who looked at animal tissues?
Pg. 51 Assignment
Write your own Level 2 Question over the Cell Theory.
Level 2 - Explain, Compare, Analyze, Infer, Give an example of
The Cell Theory
EQ: What is the importance of the cell theory and what makes a living thing?
1) What object did Robert Hooke observe under a microscope?
2) What did Leeuwenhoek see under a microscope? what did he call them?
3) What scientist looked at plant cells? Who looked at animal tissues?
OL Article Review (Pg. 50)
Fold, Cut, and Label a piece of construction paper like this...
Organ System
Confused? Wait quietly for instructions
On pg. 53, write "In the video, the human body is compared to ______________ because __________________.
Write Examples!!!
Pg. 53 Assignment
Like in the video, draw and explain your own analogy for how the body is made up of smaller parts.
"The body is made of smaller parts like a city.
Cells are like the bricks. Tissue is like the walls of buildings..."
