1. Cell Comparisons Plant vs Animal Cells

2. Prokaryotic Cells Bacteria and Archaebacteria ONLY NO Nucleus! DNA is free floating NO organelles! All chemical reactions occur in the cytoplasm All chemical reactions occur in the cytoplasm Cell Membrane and Cell Wall

3. Eukaryotic Cells Multicellular: Plants and Animals Unicellular: Protists and Algae Chemical reactions occur in specialized organelles DNA contained within a nucleus

4. Eukaryotic Cells: Plants

5. Eukaryotic Cells: Animals

6. Eukaryotic Cells: Cell Wall Plants Nonliving layer Nonliving layer Found outside the membrane Found outside the membrane Provides structure and support Provides structure and support Found in plants & bacteria Found in plants & bacteriaAnimals NO cell wall present!

7. Eukaryotic Cells: Vacuoles Plants Single large vacuole Single large vacuole Holds water Holds water Helps give shape to cells Helps give shape to cellsAnimals Lots of small ones May help with movement (protists)

8. Eukaryotic Cells: Energy Source Plants Chloroplasts Chloroplasts Contain chlorophyll Capture light energy and convert it to food energy Animals Mitochondria Transform energy stored in food into ATP

9. Eukaryotic Cells: Plant vs Animal Plants Cell wall AND cell membrane Cell wall AND cell membrane Chloroplast Chloroplast One large central vacuole One large central vacuoleAnimals No cell wall Mitochondria Several small vacuoles
