prokaryotes
unicellular organisms that lack a nucleus, bacteria and archaea
eukaryotes
multicellular (sometimes unicellular) organisms that contain a nucleus, eukarya
eukarya kingdoms
animalia, plantae, fungi, protista
taxonomy
science of classifying organism, helps us understand diversity and evolutionary history
properties of life
order, response to environment - stimuli, reproduction, adaptation, growth, regulation and homeostasis, energy and processing, evolution
bacteria
microscopic single-cell prokaryotic organisms that lack membrane bound organelles and a nucleus, can grow in any kind of environment
archaea
unicellular organisms that lack a nucleus, found in extreme environments
eukarya
unicellular or multicellular organisms that contain a nucleus
viruses
not made of cells, not eukaryote or prokaryote, no domain or kingdom, cannot replicate without help (but they have nucleic acids and can evolve)
protist
eukaryotic organisms that prefer aquatic and moist environments, motile, three appendages for movement: flagella, cilia, psuedopods
fungi
heterotrophic eukayotes that release nutrients and make nutritious food for other organisms, contain cell walls made of chitin, prefer aquatic or terrestrial environments, ex. yeast, mold, mushrooms
plants
eukaryotic autotrophs that have chloroplasts and cell walls, able to photosynthesize
animals
eukaryotic heterotrophic organisms that have no cell walls
cell wall
provide stucture and protection to plant cells, made of cellulose
hypothesis
prediction of a scientific experiment
