  1. The Microscope Do you know the parts?

  2. What is a Cell???? The Cell Theory 1) All organisms are made of cells. 2) Cells are the basic unit of structure. 3) New cells come from preexisting cells.

  3. Diversity of Cell Life All organisms fit into 2 groups: 1) unicellular- one-celled organisms 2) multicellular- many celled organism - cell differentiation/specialization - each cell has a specific function ex.- blood cells, muscle cells, nerve cells

  4. Cell Differentiation/Specialization

  5. Levels of Multicellular Organization 1) Cell 2) Tissue- similar cells working together 3) Organ- similar tissues working together 4) Organ System- groups of organs working together Digestive System Stomach Cell Stomach StomachTissue

  6. Cell Types 1) Prokaryotes - no nucleus - few organelles (cell parts) - smaller, less complex ex.- Bacteria

  7. 2) Eukaryotes - have a nucleus - many organelles - larger, more complex Examples: Plant Protist Fungi Animal

  8. CELL ORGANELLES Nucleus - controls cell’s processes - contains DNA Ribosomes - assembles amino acids into proteins Vacuoles - stores materials for the cell

  9. Mitochondria (powerhouse) • provides energy for the cell Chloroplast (plants/algae) • carries out photosynthesis Cell Membrane • allows materials to move in/out of cell Cell Wall (plants, fungi, bacteria) • provide extra protection

  10. Plant and Animal Cell Differences Plant CellAnimal Cell Contains: Cell Wall No Cell Wall Chloroplast No Chloroplast Large Vacuole Small Vacuole Shape: Square, rigid Round, fluid

  11. Plant Cell Animal Cell

  12. Cell Vocabulary Review A. Produces energy for the cell B. Controls all cell functions C. Makes proteins for the cell D. Stores materials for the cell E. Allows materials to go in/out of the cell F. Simple cell with no nucleus G.Complex cell that has a nucleus
