1. Into to cells? Objective: 1.You will be able to explain what cells are and 2. You will be able to differentiate between the 2 types of cells.

2. Warm up 1.What are cells? 2.What do cells do?

3. Word Definition Picture 1. Cell Basic functional unit of all living things (building blocks) - Tiniest part of a living thing Red blood cell Paramecium E. Coli (bacteria)

4. Cells - FYI All living things are made up of cells! (including you!) Cells do all the life functions that we do: - grow - make energy - reproduce - get rid of wastes - need food (to make energy) - die

5. Cells - FYI Cells can look very different There are many types of cells Living things can be made up of ONE CELL or MANY CELLS! There are approximately 100 trillion cells in the human body…….100,000,000,000,000 Red blood cell Paramecium E. Coli (bacteria)

6. Examples of Cells Amoeba Proteus Plant Stem Red Blood Cell Nerve Cell Bacteria

7. What are cells made of? Cells are mostly water. The rest of the present molecules are: protein nucleic acid carbohydrate lipid other

8. There are many cells but scientists classify cells into 2 types: Procaryotic cells Eukaryotic cells

9. Word Definition Picture 2. Prokaryotic cell (Prokaryote) Unicellular NO nucleus No organelles Has ribosomes Circular DNA Very very small Examples: BACTERIA E. Coli (bacteria) Strept. bacteria

10. Prokaryotic Cell

11. Did you know? Prokaryotic cells were probably the first type of cells to exist on Earth and are commonly found in the oldest fossils ever found.

12. Word Definition Picture 3. Eukaryotic cell (Eukaryote) Unicellular and Multicellular Membrane bound Nucleus Contains Organelles Has ribosomes Linear DNA Big compared to prokaryotic cells Examples: Animals, Plants, Fungi, Protists (algae) Red blood cell Human cheek cells Shark skin

13. Eukaryotic Cell

14. Did you know…. Eukaryotic cells are more complex and are larger. This type of cell has a nucleus and many organelles inside. This allows the cell to perform many different jobs in multicellular organisms!

15. Prokaryotic CellsEukaryotic Cells Unicellular or Multicellular Nucleus in cell? (yes or no) Organelles in cell? (yes or no) Does it have ribosomes? (yes or no) What type of DNA? Examples: Unicellular No nucleus No Yes Circular Bacteria Unicellular and Multicellular Yes No nucleus Linear Plant, animal, fungi, protist cells

16. Exit Slip Prokaryotes Eukaryotes What they both have in common
