1. CELLS

2. Cells The basic unit of all living things.
Are made up of “little organs” called organelles.

3. Blood cells attacking bacteria
There are many types of cells but they can all be categorized as either Prokaryotic or Eukaryotic
Skin Cells
Mold spores
Blood cells attacking bacteria
Bacteria
Paramecium
Dragonfly wing cell
Plant Leaf cells
Pollen

4. Prokaryotic
Eukaryotic

5. PROKARYOTE

6. Prokaryotes Bacteria Very small Oldest cells on Earth
Very simple: No membrane- bound organelles or nucleus
DNA circular found in cytoplasm

7. Typical Bacteria No Nucleus (DNA tangled in cell) No Chloroplasts
Have Cell Membrane
NO Mitochondria
Have Ribosomes

8. EUKARYOTE

9. Eukaryotes Any cell that is not bacteria (includes plants and animals)
Larger
Newer, more recently evolved
Have membrane-bound organelles
Have membrane bound nucleus that contains DNA in double helix.

10. Two Main Types of Eukaryotes that we are familiar with are
PLANTS and ANIMALS

11. Typical Plant Cell Has cell wall (Plant Skeleton)
Has chloroplasts (for photosynthesis)
Square shape
Have Cell Membrane
Have Mitochondria
Have Nucleus
Have Ribosomes
No Lysosomes

12. Typical Animal Cell No cell wall No chloroplasts Have Cell Membrane
Have Mitochondria
Have Nucleus
Have Ribosomes

13. ORGANELLES

14. Organelles
Cell Membrane- Acts as boundary and bouncer determining what comes in and what gets out (phospholipids)
Nucleus- Contains DNA (genetic information) “Brain of cell”
Ribosomes- Makes protein (RNA gives code from DNA –translation)
Chloroplasts- performs Photosynthesis (makes sugar from sunlight)
Mitochondria- Breaks sugars and releases usable energy
