Prokaryotes
An organism of the kingdom Monera (or Prokaryotae), comprising the bacteria and cyanobacteria, characterized by the absence of a distinct, membrane-bound nucleus or membrane-bound organelles, and by DNA that is not organized into chromosomes. Also called moneran.
bacteria
ubiquitous one-celled organisms, spherical, spiral, or rod-shaped and appearing singly or in chains, comprising the Schizomycota, a phylum of the kingdom Monera (in some classification systems the plant class Schizomycetes), various species of which are involved in fermentation, putrefaction, infectious diseases, or nitrogen fixation.
spirochetes
Any of various slender, spiral, motile bacteria of the order Spirochaetales, many of which are pathogenic, causing syphilis, relapsing fever, yaws, and other diseases.
cyanobacteria
blue-green algae
extremophiles
An organism adapted to living in conditions of extreme temperature, pressure, or chemical concentration, as in highly acidic or salty environments.
thermophiles
a thermophilic organism
halophiles
An organism that requires a salty environment.
methanogens
Any of various archaea that are capable of producing methane from the decomposition of organic material
algae
any of numerous groups of chlorophyll-containing, mainly aquatic eukaryotic organisms ranging from microscopic single-celled forms to multicellular forms 100 ft. (30 m) or more long, distinguished from plants by the absence of true roots, stems, and leaves and by a lack of nonreproductive cells in the reproductive structures: classified into the six phyla Euglenophyta, Crysophyta, Pyrrophyta, Chlorophyta, Phaeophyta, and Rhodophyta.
dinoflagellates
Any of numerous minute, chiefly marine protozoans of the order Dinoflagellata, characteristically having two flagella and a cellulose covering and forming one of the chief constituents of plankton. They include bioluminescent forms and forms that produce red tide.
amoebozoans
infection by a disease-causing ameba
ciliates
Any of various protozoans of the class Ciliata, characterized by numerous cilia
diatoms
Any of various microscopic one-celled or colonial algae of the class Bacillariophyceae, having cell walls of silica consisting of two interlocking symmetrical valves.
heterotrophs
An organism that cannot synthesize its own food and is dependent on complex organic substances for nutrition.
photosynthetic
the synthesis of complex organic materials, esp. carbohydrates, from carbon dioxide, water, and inorganic salts, using sunlight as the source of energy and with the aid of chlorophyll and associated pigments.
eukaryotes
A single-celled or multicellular organism whose cells contain a distinct membrane-bound nucleus.
Bryophytes
seedless non-vascular, dominant gametophyte
ferns
seedless vascular, dominant sporophyte, free-living gametophyte
gymnosperm (conifers
pollen, naked seeds, vascular, reduced dependent gametophyte
angiosperm: (flowering
): pollen, flowers, fruit, seeds, reduced dependent gametophyte, monocot vs. dicot
porifera
an animal phylum comprising the sponges
sponges
Any of numerous aquatic, chiefly marine invertebrate animals of the phylum Porifera, characteristically having a porous skeleton composed of fibrous material or siliceous or calcareous spicules and often forming irregularly shaped colonies attached to an underwater surface.
The light, fibrous, flexible, absorbent skeleton of certain of these organisms, used for bathing, cleaning, and other purposes.
Porous plastics, rubber, cellulose, or other material, similar in absorbency to this skeleton and used for the same purposes.
Metal in a porous, brittle form, as after the removal of other metals in processing, used as a raw material in manufacturing.
Informal A glutton.
Slang A drunkard.
radials
Of, relating to, or arranged like rays or radii.
Radiating from or converging to a common center.
Having or characterized by parts so arranged or so radiating.
Moving or directed along a radius.
Anatomy Of, relating to, or near the radius or forearm.
Developing symmetrically about a central point.
cnidaria (jellyfish, hydra, corals):
an alternative name for the invertebrate phylum Coelenterata, giving emphasis to the stinging structures as characteristic of the phylum.
