  1. Unit 2 Biology NotesCell Theory Objective 2: Explain the components of the cell theory.

  2. Cell Theory One of the most fundamental concepts of biology states: • All living things are composed of cells. • Cells are the basic units of structure and function in living things. • New cells are produced from existing cells.

  3. Unit 2 Biology NotesCell Parts Objective 3: Identify and explain the major functions of the following cell parts: Nucleus, Cell Membrane, Cell Wall, Chloroplast, Mitochondria, Ribosome, and Vacuole

  4. Use the following colors to color the plant and animal cell pictures: • Plant Cell: • 1- light blue • 2- brown • 5- dark blue • 6- black • 8- pink • 10- purple • 11- green • 12- orange • 13- light yellow • Animal Cell: • 1- orange • 4- dark blue • 5- black • 6- pink • 8- light blue • 9- light yellow • 11- purple

  5. Cell Types Specialized structures that perform important cellular functions

  6. Cell Parts • 1- Cell Wall • 2- Cell Membrane • 3- Mitochondria • 4- Vacuole • 6- Cytoplasm • 8- Nucleolus • 9- Nucleus • 11- Ribosome • 12- Chloroplast

  7. Label the structures on the plant and animal cell pictures: • Plant Cell: • 1- Vacuole • 2- Cell Wall • 5- Nucleus • 6- Ribosome • 8- Cell Membrane • 10- Nucleolus • 11- Chloroplast • 12- Mitochondria • 13- Cytoplasm • Animal Cell: • 1- Mitochondria • 4- Nucleus • 5- Ribosome • 6- Cell Membrane • 8- Vacuole • 9- Cytoplasm • 11- Nucleolus

  8. Unit 2 Biology NotesAnimal Cells vs. Plant Cells Objective 5: Use two characteristics to distinguish between animal and plant cells. Presence of Cell Wall Presence of Chloroplasts

  9. Animal Cell Nucleus Ribosome (free) Cell membrane Ribosome (attached) Mitochondrion

  10. Animal Cell

  11. Plant Cell Nucleus Ribosome (free) Ribosome (attached) Cell wall Cell membrane Chloroplast Mitochondrion Vacuole

  12. Plant Cell

  13. Plant Cell Animal Cell

  14. Unit 2 Biology NotesCell Types Objective 5: List and use 3 characteristics to distinguish prokaryotic and eukaryotic cells.

  15. Cell Types • Cells are divided into two major categories: Prokaryotes and Eukaryotes. • Major Characteristics of These Types of Cells

  16. Prokaryotic Cell Cell membrane cytoplasm
