Do Kangaroos Prefer Chocolate Or Fruit Generally Speaking?
Prokaryotic
Unicellular
Some of the first life forms on Earth
Mostly found in 3 shapes – spheres, rods and spirals
Contains a cell wall (amino acids)
Ribosomes (70S sedimentation rate)
Eg. Gut flora, syphallis, Lactococcus
Bacteria
Prokaryotic
Unicellular
More closely related to Eukarya
Live in some of the most extreme conditions on Earth
Cell wall (proteins – different from bacteria)
Ribosomes (16S sedimentation rate)
Eg. Help in element cycling, mutualism with animals
Archae
EukaryoticUnicellular or MulticellularMost complex life formsCell walls (chitin or cellulose)Ribosomes (80S sedimentation rate)Eg. Amoebas, grasses, mushrooms,
elephants
Eukarya
Unicellular or multicellular
Contains a membrane bound nucleus and mitochondria
Organelles!
Eukaryotes
Unicellular
Does not contain a nucleus or mitochondria
Lacks membrane bound organelles (ER, golgi bodies, etc.)
Prokaryotes
Prokaryotes vs. Eukaryotes
Eukaryotic, unicellular
Autotrophic or heterotrophic
No cell wall
Eg. Slime molds, Euglena, Paramecium
There are animal-like protists as well as plant-like protists
Cause of Malaria
Kingdom Protista
Eukaryotic, multicellular
Heterotrophic (decomposers)
Cell wall made mostly of chitin
Eg. Mold, Yeast, mushrooms, Athlete’s foot, Penecillium
Made up of a mass of small filaments (hypae)
“eat” by secreting digestive enzymes
Kingdom Fungi
Eukaryotic, multicellular
Autotrophic
Cell wall of cellulose
Eg. Green algae, moss, ferns, flowering plants, trees
Contain chloroplasts
Kingdom Plantae
Eukaryotic, multicellularAutotrophicNo cell wallsEg. termites, seahorses, snakes, goats, gorillas
Kingdom Animalia
On a blank piece of paper create a word web of all terms involved with ecosystems
What is an Ecosystem?
Abiotic and biotic features of a given area
Eg. temperature levels, rainfall, soil types, animals, plants
All organisms in an ecosystem referred to as a community
Changes in ecosystem over time = ecological succession
