1. Turn your homework in.
Get out your notebooks. Open to page 16.

2. Characteristics of living things
Unicellular vs Multicellular
Autotrophic vs Heterotrophic
Prokaryotic vs Eukaryotic

3. Unicellular Composed of one cell
Examples: Bacteria, blue-green algae, Paramecium, Euglena, Amoeba

4. Multicellular Composed of more than one cell
Examples: Blackworm, Wisconsin Fast Plant, Volvox

5. Autotrophic “Self-feeder” – organisms that can make their own food
Examples: plants and photosynthesis

6. Heterotrophic “Other-feeder” – organisms that eat other organisms
Examples: herbivores, omnivores, carnivores

7. Prokaryotic Does not contain a defined nucleus
Organelles: CELL MEMBRANE, CYTOPLASM, RIBOSOMES
DNA in CYTOPLASM
1st to evolve about 4 billion years ago
Kingdoms: Moneran (Bacteria & Archaea)

8. Eukaryotic Does contain a defined nucleus
Organelles: CELL MEMBRANE, CYTOPLASM, RIBOSOMES, NUCLEUS, ENDOPLASMIC RETICULUM (ER), GOLGI BODY, VACUOLE, MITOCHONDRIA
DNA in NUCLEUS
Evolved from PROKARYOTES about 1 billion years ago
Kingdoms: PROTISTA (Protist), PLANTAE (PLANT), FUNGI, ANIMALIA (ANIMAL)
