Eukaryotic Cells
contain a nucleus and organelles bound by plasma membranes
Prokaryotic Cells
do not have a membrane-bound nucleus or organelles
Carl Woese
(1977) he proposed a system of classification that divides all organisms into three domains of life
"domain" becomes the highest taxonomic group
Archaea, Bacteria, and Eukarya
Three Domains of Life
Domain Archaea
Kingdom Archaebacteria
Domain Bacteria
Kingdom Eubacteria
Domain Eukarya
Kingdom Protista
Kingdom Fungi
Kingdom Plantae
Kingdom Animalia
Kingdom Archaebacteria
extremophiles
single-celled bacteria living in extreme environments
believed to be the oldest life-forms on Earth
Kingdom Eubacteria
contains all single-celled prokaryotes except archaebacteria
three basic forms:
-> coccus - spherical
-> bacillus - rod-shaped
-> spirillum - spiral
Kingdom Protista
most diverse among unicellular eukaryotic organisms
mostly unicellular, few are colonial and multicellular
some are autotrophs, others are heterotrophs
animal, plant, fungus, or colonial algae
Kingdom Fungi
well-adapted to absorptive nutrition
mostly multicellular except for yeast
breakdown substances in their surroundings
heterotrophic
Kingdom Plantae
multicellular eukaryotes
naturally green, have cell walls, cannot move, and use the sun's energy to make sugar
all autotrophs
In Kingdom Plantae: Plants with seeds - Angiosperms

These organisms have seeds enclosed in the ovary (fruit); with flowers
In Kingdom Plantae: Plants with seeds - Gymnosperms

These organisms have their seeds exposed (no fruit); no flowers
In Kingdom Plantae: Angiosperms

monocots and dicots
these are examples of..
In Kingdom Plantae: Gymnosperms

pine tree, cycad, and ginkgo

these are examples of..
In Kingdom Plantae: Plants without seeds but with spores

club moss, fern, and horsetails
Kingdom Animalia
multicellular without cell walls or chlorophyll
can usually move and quickly respond to the environment
all heterotrophs
