  1. What do we know about cells? • We know that all living things require cells • Is there a relationship in terms of size, shape, components? • Seven different cells of various cell types

  2. In Lab book • Purpose: • Hypothesis • Statement + because • Materials and Method: See Cellabration Handout

  3. Data • Picture of each cell type under low and High Power • Estimation of size • Observations • Shape • Inside components • Similarities between other cell types

  4. What did you discover in the lab? In regards to: • Similarities between cells • Difference between cells

  5. What did you discover in the lab in regards to • Cell Size • Shape

  6. What did you discover in the lab in regards to • The internal “circle”

  7. All living things need cells • The organelles (or parts) of cells allow the characteristics of life to be met • There are different types of cells which meet these qualifications in different ways

  8. There are characteristics that we use to group different cells with different organelles. • If cells do not have a nucleus they are called Prokaryotic Cells • If cells do have a nucleus they are called Eukaryotic Cells.

  9. The Nucleus • Is the control Center of the cell. It is the Boss and Brain. • All genetic information is kept here thus instructions for making proteins and other necessities. • It is often seen as a large Circle under the microscope

  10. Which of the slides do you believe were Eukaryotes? • A.Clostridiumbotulinum and Bacillus Cereua • B.Elodea,Potato, Cheek Cell, Onion Cell, Euglena

  11. Animal Cells/ Plant Cells are both Eukaryotes! As well As Protists…. Bacteria is not!

  12. Animal Cells/ Plant Cells have many things in common

  13. Mitochondria • If a cell was a car, gas would be created here! • Allows the cell to use and maintain energy • Respiration occurs here. (Oxygen added to proteins to create energy in the form of ATP (energy!)

  14. Ribosomes • Make Proteins! • Proteins do different things such a • control the rate of reactions in the cell • regulate cell processes, • form bones and muscles or transport things in and out of the cell. • Ex: Lactase allows your body to digest milk

  15. Endoplasmic Reticulum • Allows cells to use and obtain materials • Channel or tube which materials are transported through the cell • Helps to make proteins and Lipids

  16. Vacuoles • The storage closet! • Maintains the correct pressure for the cell in plants so that they don’t explode or burst

  17. Some organelles are unique to plant and Bacteria cells • Cell Walls are present in plant and bacteria cells for support • They are like the walls of a house and give the cells a rigid shape! • Chloroplasts are unique to some plant and bacteria cells to use energy from the sun. • Contain Clorophyll Gives Cells a • Green color

  18. Which of the Samples do you believe were animal cells?Remember Animal Cellshave a less rigid shape/a nucleus/ no chloroplasts • A. Clostridium botulinum and Elodea • B. Cheek Cell • C. Bacillus Cereus and Euglena • D. Onion Cell

  19. Which of the Samples do you believe were plant cells?Remember Plant cellshave a rigid shape/a nucleus/ and sometimes chloroplasts A.Clostridiumbotulinum/ Cheek Cells B.Elodea/Potato Cells/Onion Cells C.Cheek Cell/Bacillus Cereus D.Elodea/Euglena

  20. Why would the potato/Onion cells not have chloroplasts? A.It is not a plant cell B.It is not a part of the plant that photosynthesizes C.I’m not sure

  21. Do you think the Euglena had chloroplasts? • A. Yes • B. No

  22. Bacteria Cells are unique! they are Prokaryotes and have no Nucleus! They keep their DNA in the nucleoid. They have some things in common with plant and animal cells to allow them to liveOther things are different

  23. They move/Reproduce in unique ways • Some have Flagella to help them move- Like a whip • They have a pilli which enables them to hook on to other cells and reproduce. • They have a capsule which they use for protection.

  24. Which of the Samples do you believe were bacteria cells? A.Clostridiumbotulinum/ BacillusCereus B.Elodea/Potato C.Cheek Cell/Euglena/Onion Cells

  25. To recap: • All cells are required for living things • Animal/Plant cells are Eukaryotes(Have Nucleus) • Bacteria are not Eukaryotes • All have some organelles in common • All have some organelles that are different You are required to know that ones we discussed in class

  26. You will create lyrics for a song, write a poem or another creative activity approved by Miss H • You will be graded by incorporating the important organelles of the cell you choose and describe how these organelles allow them to meet life processes Creating a presentation which displays creativity and care • You will work in groups up of 4. • Each member will receive the same grade
