Characteristics of living things Unicellular vs Multicellular Autotrophic vs Heterotrophic Prokaryotic vs Eukaryotic
Unicellular Composed of one cell Examples: Bacteria, blue-green algae, Paramecium, Euglena, Amoeba
Multicellular Composed of more than one cell Examples: Blackworm, Wisconsin Fast Plant, Volvox
Autotrophic “Self-feeder” – organisms that can make their own food Examples: plants and photosynthesis
Heterotrophic “Other-feeder” – organisms that eat other organisms Examples: herbivores, omnivores, carnivores
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)
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)
