The 3 Domains

Bacteria u. Prokaryotic u. Unicellular u. Some u. Mostly of the first life forms on Earth found in 3 shapes – spheres, rods and spirals u. Contains a cell wall (amino acids) u. Ribosomes u. Eg. (70 S sedimentation rate) Gut flora, syphallis, Lactococcus

Archae u. Prokaryotic u. Unicellular u. More u. Live u closely related to Eukarya in some of the most extreme conditions on Earth Cell wall (proteins – different from bacteria) u. Ribosomes u. Eg. (16 S sedimentation rate) Help in element cycling, mutualism with animals

Eukarya u. Eukaryotic u. Unicellular u. Most u. Cell or Multicellular complex life forms walls (chitin or cellulose) u. Ribosomes u. Eg. (80 S sedimentation rate) Amoebas, grasses, mushrooms, elephants

Prokaryotes vs. Eukaryotes Prokaryotes Eukaryotes u. Unicellular u. Does not contain a nucleus or mitochondria u. Lacks membrane bound organelles (ER, golgi bodies, etc. ) or multicellular u. Contains a membrane bound nucleus and mitochondria u. Organelles!

Kingdom Protista u. Eukaryotic, unicellular u. Autotrophic or heterotrophic u. No cell wall u. Eg. Slime molds, Euglena, Paramecium u. There animal-like protists as well as plant-like protists u. Cause of Malaria

Kingdom Fungi u. Eukaryotic, multicellular u. Heterotrophic u. Cell (decomposers) wall made mostly of chitin u. Eg. Mold, Yeast, mushrooms, Athlete’s foot, Penecillium u. Made u“eat” up of a mass of small filaments (hypae) by secreting digestive enzymes

Kingdom Plantae u. Eukaryotic, multicellular u. Autotrophic u. Cell wall of cellulose u. Eg. Green algae, moss, ferns, flowering plants, trees u. Contain chloroplasts

Kingdom Animalia u. Eukaryotic, multicellular u. Autotrophic u. No cell walls u. Eg. termites, seahorses, usnakes, goats, gorillas

Intro to Ecology

What is an Ecosystem? u. On a blank piece of paper create a word web of all terms involved with ecosystems

Ecosystem u. Abiotic and biotic features of a given area u. Eg. temperature levels, rainfall, soil types, animals, plants All organisms in an ecosystem referred to as a community u u. Changes in ecosystem over time = ecological succession
