Kingdoms of Living Things
Bacteria Prokaryotes Unicellular Autotrophic or heterotrophic 2 Domains of bacteria
*Domain Archaea Kingdom Archaebacteria—live in harsh places, such as geysers, glaciers, undersea volcanoes
*Domain Bacteria Kingdom Eubacteria—live almost everywhere else (ubiquitous) -Can be symbiotic—live in/with another organism -Most are very helpful!
Some are pathogenic—cause disease. Strep bacteria Staph bacteria
3 Common bacterial shapes: Spherical—called coccus Rod-shaped—called bacillus Spiral-shaped—called spirillum
Spherical Bacteria
Rod-shaped Bacteria
Spiral Bacteria
Bacterial Reproduction Binary fission— asexual method similar to mitosis
Conjugation— “sexual” method; swapping of DNA through a sex pilus
Domain Eukarya All eukaryotes
Kingdom Protista/Protists Eukaryotes Autotrophic or heterotrophic Mostly unicellular Live in aquatic or moist places Can be animal- like, plant-like, or fungus-like
Paramecium
Euglena
Amoeba
Most protists are free-living, but some are parasites, causing such diseases as malaria and Giardia.
Protist Reproduction Binary or Multiple Fission—asexual Fragmentation—asexual—part of an individual breaks off and becomes a new individual Budding—asexual—a growth falls off and becomes a new individual Sexual methods: conjugation, sex cell formation
Kingdom Fungi Eukaryotes Heterotrophic Mostly multicellular Live in moist, dark places
Fungi: Decompose food by extracellular digestion—digest food around them, then absorb it Decomposers are also called saprophytes or saprobes.
Fungi have cell walls made of chitin. Fungi examples include: yeast (budding)
mushrooms morels
bracket fungi puffballs
A few fungi can be parasitic, such as the one that causes ringworm.
Fungi Reproduction Budding—in yeast—asexual Fragmentation—asexual Spores—asexual Sexual—two types of hyphae (+ and – ) fuse
Use Plant PP and Animal PP INSTEAD of the following slides!!
Plants Eukaryotes Autotrophic Multicellular Stationary Have organs and systems
2 Main groups of plants: 1. Nonvascular—no transport system 2. Vascular—have transport systems
Plant examples: moss ferns
trees (spruce) flowering plants
Animals Eukaryotes Heterotrophic Multicellular Can move on their own Have complex organs and systems
2 Main Groups of Animals: 1. Invertebrates—no backbone There are many invertebrate phyla. 2. Vertebrates—have a backbone Vertebrates are classified into Phylum Chordata.
Animal examples: earthworms elephants
sponges killer whales
