second highest taxonomic classification of organisms, after domain

Front 2

monera

Back 2

protoctista

Back 3

kingdom composed of eukaryotic microorganisms and their immediate descendants, such as slime molds and protozoa

Front 4

fungi

Back 4

kingdom of eukaryotic organisms that lack vascular tissues and chlorophyll, possessing chitinous cell walls; reproduction occurs through spores

Front 5

plantae

Back 5

kingdom containing all extinct and living plants

Front 6

animalia

Back 6

kingdom that includes all extinct and living animals

Front 7

archea

Back 7

kingdom comprised of an ancient group of microorganisms (bacteria) that a re metabolically and genetically different from other bacteria; they came before the eukaryotes

Front 8

bacteria

Back 8

kingdom of single-celled organisms that reproduce by fission and can be spiral, rod, or spherical shaped; often pathogenic organisms that rapidly reproduce

Back 17

phylum of cone-bearing gymnosperm trees and shrubs that are primarily needle- and scale-leaved

Front 18

angiosperms

Back 18

a flowering plant; a plant of the class angiospermae that produces seeds enclosed in an ovary and is characterized by the possession of fruit and flowers

Front 19

radial symmetry

Back 19

symmetrical arrangement of radiating parts about a central point

the equal division of an organism into a left and right half

Front 21

spicules

Back 21

small needlelike structures that support the soft tissue of some invertebrates, such as sponges

Front 22

coelom

Back 22

the space between the mesodermal layers that forms the body cavity of some animal phyla

Front 23

acoelomate

Back 23

an animal that lacks a coelom, exhibits bilateral symmetry, and has one internal space, the digestive cavity

Front 24

pseudocoelomates

Back 24

organisms with fluid-filled body cavity surrounding the gut

Front 25

coelomates

Back 25

organisms that contain a coelom
