Ticket out the door! Summarize the cell theory and how these 5 scientists help create it! HOMEWORK: HAVE A GREAT 4 DAY WEEKEND!
Biology: Please get out your composition notebook, or something to write on. Today: Oct 15 Bellringer Stations: Compare and Contrast Eukaryotic Cells to Prokaryotic Cells Compare and Contrast Animal and Plant cell structure Quiz Friday on Compare and Contrast Euk/Pro Animal/Plant
BELLRINGER: Explain how each of the five scientists contributed to the cell theory. (Try it without looking in your notes!)
Biology: Please get out your station handout from yesterday and your textbook! Today: Oct 16 Stations: Compare and Contrast Eukaryotic Cells to Prokaryotic Cells Compare and Contrast Animal and Plant cell structure Quiz Friday on Compare and Contrast Euk/Pro Animal/Plant Cell Theory
QUIZ FRIDAY!!!! You will be sent to work at stations in groups of 4. If you are not at a station, then you will work on Cells and their organelles packet! When you find answers, write them down AND underline or high lite information in the text! Don’t forget to color cell model…Directions are IN THE READING!!!
Get out your vocab assessment!*Grab the Notes Sheet from side table! BrainWork #12 What do you know about cells? *sorry I do not have all of your tests graded yet, I am waiting on some people to take them!
Number 1-10 in your notes. For each statement hypothesize if it is True or False. Do not re-write the statements.
Some Random Cell Facts • The average human being is composed of around 100 Trillion individual cells!!! • It would take as many as 50 cells to cover the area of a dot on the letter “i” WOW!!!
I.Cell Theory A. 1665- Robert Hooke- used microscope to see cork cells- named them “cells” *Hooke named them this because he believed they looked like the little rooms monks lived in at monasteries which were called cells.
B. 1673 Anton van Leeuwenhoek- Used a handmade microscope to observe pond scum & discovered single-celled organisms • He called them “animalcules” • He was the first to make a simple light microscope.
Development of Cell Theory D. 1838- Matthias Schleiden (German Botanist) -Concluded that all plant parts are made of cells E. 1839- Theodor Schwann (German physiologist) -Stated that all animal tissues are composed of cells.
F. 1858- Rudolf Virchow (German physician) -Concluded that cells must arise from pre-existing cells.
3 Parts of the cell theory: All living things are composed of cells B. Cells are the basic units of structure and function New cells are produced from existing cells Cell Theory Song! http://www.youtube.com/watch?v=KuJqqiATlqw
How Has The Cell Theory Been Used? • The basic discovered truths about cells, listed in the Cell Theory, are the basis for things such as: • Disease/Health/Medical Research and Cures(AIDS, Cancer, Vaccines, Cloning, Stem Cell Research, etc.)
Biology: Please put your station sheets on your desk… Then get out a sheet of paper! Today: Oct 17 Check Station Sheets Review Compare and Contrast Types of Cells! Quiz tomorrow: Cell Theory, Compare and Contrast Types of Cells!
What are the differences? Eukaryotic Cell
Cells are divided into two categories: 1. Prokaryotes a. much smaller and simpler, no organelles b. no membrane bound nuclei c. contain cell membrane, DNA, cytoplasm ex: bacteria
2. Eukaryotes- more complex! a. contain many organelles, larger, true nucleus 1.) organelle- specialized structure that has a specific function (in cell) b. All plants, animals, and fungi are eukaryotes *all our cells are Eukaryotic!
1. Label each side of the venn diagramA B - Large & Complex - Contain Nucleus • Membrane-bound organelles • Make up plants, animals, fungi, and protists • Small & simple • No nucleus • No organelles • Bacteria - Cell membrane • Contain DNA - Cytoplasm
2. What type of cell is this? 3. Name one reason you know it is this type of cell 4. This cell has whip-like flagellum, what do you think those might be used for? 5. Do you think it would be more likely to assume this is a bacteria or plant cell? Why?
Cell membrane 6. What type of cell is this? (prokaryotic/eukaryotic?) Name one thing about this cell that helped you know it was that type of cell: Do you think this is more likely a plant cell or an e-coli cell?
Similarities: • All eukaryotic cells have a cell membrane, nucleus, and cytoplasm.
Both Plant and Animal cells have vacuoles, however, Plant cells have VERY LARGE vacuoles, while animal cells have many small vacuoles.
ØPlant cells contain many of the same organelles you would find in an animal cell with the exception of a few key players Ø(1)Cell Walls and (2)Chloroplasts are found in plant cells and not animal cells.
Work on filling out the review sheet for quiz!!! HW: STUDY FOR QUIZ!
Biology: Get out your review sheet and STUDY!!!! Today Oct 18: Friday Mythbusters!--Collect Hall Passes Study for quiz! QUIZ!!! Finish Cell Packet...This includes the coloring and labeling!!
Biology: Please turn in your cell packets to basket--before BELL! Today: Oct 21: Describe cell organelle functions! (Groups) If you were absent FRIDAY you need to take a quiz for me! YOU NEED YOUR TEXTBOOKS TODAY!!!!
Due: Reading Questions…Get out and put on YOUR desk! BrainWork #13 Without looking in your notes… What are the 3 parts to the cell theory?? Objective for today: Compare and Contrast Prokaryotic cells to Eukaryotic cells
2 main types of microscope: 1. Electron microscopes: a. forms an image of a specimen using a beam of electrons rather than light b. Specimen placed in a vacuum so no living samples are used Microscopes
2. Light microscopes- a. uses two lenses b. light from the base shines up through the specimen c. Ocular lens is 10x, objective lens is either 10x, or 40x Ex: What is the magnification of an object which uses the 40x objective lens? Ocular 10x * Objective 40x= 400x
*PICK UP SHEET FROM SIDE* 9/19 Due: Nothing BRAINWORK #14? Compare and Contrast a Prokaryotic cell to a Eukaryotic cell Objective of the Day: Osmosis and Diffusion
Biology: Please get out your cell comparison from yesterday! Today Oct 24: Share videos from last year! Compare a cell to a system… These are due at the end of the hour! Make sure you explain why each part shows the function of the organelle! Draw picture and label parts/organelles If you finish early, start working on extra credit!! Cell Organelle/Function Quiz Wednesday Extra Credit DUE TUESDAY!!!! Absent yesterday? See me!

E H F D BELLWORK LABEL A-H Describe the function of each! G C B A
Organelle Foldable Outer Flap: Name of Organelle Middle (inner) Flap: Picture representing the function Center fold: Function of organelle… YOUR OWN WORDS!
Cell Structures A. Cell membrane –thin, flexible barrier around cell B. Cytoplasm- jelly-like material in-between the cell membrane and nuclear membrane ( all organelles reside in the cytoplasm) C. Cytoskeleton- protein filaments that help to maintain cell shape-flexible framework 1.) Microtubules (bigger)- hollow tubes, shape cell and help organelles move *used to make cilia and flagella 2.) Microfilaments (smaller)- very narrow-help shape and move the cell *making of and breaking down of microfilaments causes the cytoplasm to change shape, moving organisms like amoebas
Biology: Please pick up notes sheet from FRONT of room! EXTRA CREDIT IS DUE!!! Today Oct 29: Describe Diffusion Read text and define terms Cell Organelle Function Quiz TOMORROW!!
Cell membrane A. Cell membrane- controls what enters and leaves the cell 1. Lipid bilayer- double layer of phospholipids a. phosphate head and two fatty acid tails B. Proteins go through the bilayerworking as channels and pumps
C. Movement of molecules 1. Concentration- the mass of a solute in a given volume of solution ex: 12 grams of sugar in 3 liters of water (4 grams/Liter) 2. Diffusion-Molecules move from high to low concentration as they try toreach equilibrium b. Diffusion uses no energy from the cell
