Eubacteria
This domain includes prokaryotes, true bacteria. It is also a name of a kingdom.
Archaea
This domain includes prokaryotes that are bacteria that live in extreme environments. The kingdom has the same name, archaeabacteria.
Eukarya
This domain includes eukaryotic organisms
Animalia
This kingdom is eukaryotic, heterotrophic, and has no cell wall
Plantae
This kingdom is eukaryotic, autotrophic, has a cell wall and chloroplasts
Protista
This kingdom is eukaryotic and always unicellular, can be autotrophic or heterotrophic
Fungi
This kingdom is eukaryotic, heterotrophic, and has cell walls
eukaryote
cell type that has DNA enclosed in nucleus and membrane-bound organelles
prokaryote
cell type that does not have DNA enclosed in nucleus and membrane-bound organelles
taxonomy
The scientific study of how living things are classified
systematics
the science of naming and grouping organisms, same as taxonomy
Carolus Linnaeus
Father of taxonomy, Karl von Linne
multicellular
Consisting of many cells
unicellular
Made of a single cell
autotroph
An organism that makes its own food
heterotroph
organism that obtains energy from the foods it consumes; also called a consumer
bilateral symmetry
Body plan in which only a single, imaginary line can divide the body into two equal halves, L/R mirror images.
Bilateral symmetry example
butterfly
radial symmetry
The quality of having many lines of symmetry that all pass through a central point.
Radical symmetry example
jelly fish
asymmetry
no symmetry
Example of asymmetry
sponge
deuterostome
Group of animals defined by its embryonic development, in which anus forms first from blastopore and there is radial, indeterminate cleavage of cells
protostome
Embryonic development when mouth develops first from the blastopore, with spiral, determinate cleavage of cells.
diploblastic
Body parts are organized into layers derived from two embryonic tissue layers
Example of diploblastic
sea anemone
ectoderm
outer layer, epithelial and muscular muscles
endoderm
gut cavity, digestive and muscular cells
What is in between the endoderm and ectoderm?
mesoglea
triploblastic
has three tissue layers: the ectoderm, endoderm, and mesoderm.
What does the mesoderm give rise to?
gives rise to supportive, contractile and blood cells
What type of symmetry is triploblastic
usually bilateral symmetrical
Example of tirploblastic
humans and earth worms
cephalization
formation of a head, only in bilaterally symmetrical animals
coelomate
animal with a body cavity located entirely within the mesoderm
acoelomate
no body cavity
example of acoelmate
flat worm
pseudocoelomate
Characteristic when organism's organs lie free; it does not have an internal body cavity completely lined by mesoderm
Example of pseudocoelomate
roundworm
cladogram
Diagram that shows the evolutionary relationships among a group of organisms
derived character
trait that appears in recent parts of a lineage, but not in its older members
