protists
Any of a group of eukaryotic organisms belonging to the kingdom Protista according to some widely used modern taxonomic systems. The protists include a variety of unicellular, coenocytic, colonial, and multicellular organisms, such as the protozoans, slime molds, brown algae, and red algae.
photosynthetic
relating to or using or formed by photosynthesis
eukaryotes
A single-celled or multicellular organism whose cells contain a distinct membrane-bound nucleus.
monera
The kingdom of single-celled organisms without a cell nucleus (see also prokaryotes). Monera are the most primitive living things and are thought to have been the first to evolve.
bryophytes
A plant of the Bryophyta, a division of photosynthetic, chiefly terrestrial, nonvascular plants, including the mosses, liverworts, and hornworts.
fungi
a taxonomic kingdom, or in some classification schemes a division of the kingdom Plantae, comprising all the fungus groups and sometimes also the slime molds.
plants
Any of a wide variety of multicellular eukaryotic organisms, belonging to the kingdom Plantae and including the bryophytes and vascular plants.
animals
A multicellular organism of the kingdom Animalia, differing from plants in certain typical characteristics such as capacity for locomotion, nonphotosynthetic metabolism, pronounced response to stimuli, restricted growth, and fixed bodily structure.
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
Any of the unicellular prokaryotic microorganisms of the class Schizomycetes, which vary in terms of morphology, oxygen and nutritional requirements, and motility, and may be free-living, saprophytic, or pathogenic in plants or animals
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
predominantly photosynthetic prokaryotic organisms containing a blue pigment in addition to chlorophyll; occur singly or in colonies in diverse habitats; important as phytoplankton
thermophiles
Requiring high temperatures for normal development, as certain bacteria.
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.
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.
radials
Radiating from or converging to a common center.
mollusks
Any of numerous chiefly marine invertebrates of the phylum Mollusca, typically having a soft unsegmented body, a mantle, and a protective calcareous shell and including the edible shellfish and the snails.
flatworms
Any of various parasitic and nonparasitic worms of the phylum Platyhelminthes, such as a tapeworm or a planarian, characteristically having a soft, flat, bilaterally symmetrical body and no body cavity. Also called platyhelminth.
vertebrates
A member of the subphylum Vertebrata, a primary division of the phylum Chordata that includes the fishes, amphibians, reptiles, birds, and mammals, all of which are characterized by a segmented spinal column and a distinct well-differentiated head.
invertebrates
An animal, such as an insect or mollusk, that lacks a backbone or spinal column.
arthropods
Any of numerous invertebrate animals of the phylum Arthropoda, including the insects, crustaceans, arachnids, and myriapods, that are characterized by a chitinous exoskeleton and a segmented body to which jointed appendages are articulated in pairs.
annelids
Any of various worms or wormlike animals of the phylum Annelida, characterized by an elongated, cylindrical, segmented body and including the earthworm and leech.
brachiopods
Any of various marine invertebrates of the phylum Brachiopoda, having bivalve dorsal and ventral shells enclosing a pair of tentacled, armlike structures that are used to sweep minute food particles into the mouth. Also called lampshell.
algae
Any of various chiefly aquatic, eukaryotic, photosynthetic organisms, ranging in size from single-celled forms to the giant kelp. Algae were once considered to be plants but are now classified separately because they lack true roots, stems, leaves, and embryos.
cnidaria
jellyfish,hydra,corals
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.
