the smallest of the green, chlorophyll-containing plants, lack stemlike, rootlike, and leaflike structures
autotrophs-any organism that can make its own food (all green plants and certain bacteria and protozoa)l also called a producer

heterotrophs-any organism that must obtain its food from a source outside itself
autotrophs and heterotrophs
tiny, single-celled organisms with a prokaryotic cell structure
a type of club fungus that grows slowly and lacks gills; also called shelf fungus
bracket fungi (shelf fungi)
any of a group of nonvascular plants with simple leaflike, rootlike, and stemlike parts; includes mosses and liverworts
any of a group of fungus that produce spores in microscopic club-shaped structures called basidia; examples include mushrooms and toadstools, shelf or bracket fungi, rusts, and smuts
club fungi and sac fungi
a gymnospern that bears cones
a group of photosynthetic bacteria that form colonies superficially resembling those of unicellular algae; examples include Nostoc and Anabaena; also known as blue-green algae
any of a group of yellow algae characterized by ornate microscopic "shells" made of silica
a group of one-celled, photosynthetic aquatic organisms characterized by the presence of two unlike flagella; often classified as algae in the subphylum Pyrrophyta; one kind is responsible for "red tide"
eukaryote-any organism whose cells have membrane-enclosed nuclie and organelles

prokaryotes-any organism whose cells lack membrane-enclosed nuclei and organelles
eukaryotes and prokaryotes

a nonvascular plant without chlorophyll that is dependent upon other organisms for food

fungi (plural)
a nonflowering seed plant that reproduces by seeds not covered by the walls of an ovary
a group or similar organisms that are all descended from a single group of originally created animals; although often identified with the taxonomic species, the Biblical Kind may refer to a species, a genus, or a family in some cases
a combination of a fungus and an alga (or sometimes a cyanobacterium) that acts like a single organism
a nonvascular plant that has simple leaflike, rootlike, and stemlike parts
a nonvascular plant that has simple leaflike, rootlike, and stemlike parts; sometimes called true mosses to distinguish from club mosses
microorganisms (largely algae) that float near the surface of the water and provide food for larger organisms
primary consumers-in a food chain, the animals that eat food-producing green plants (producers)

secondary consumers- in a food chain, the animals that eat primary consumers
primary and secondary consumers
any of a number of jellylike, saprophytic organisms often seen on the bark of fallen trees
slime molds
a tiney, one-celled asexual reproductive structure able to grow into a new organism under the right conditions
an arrangement (as in lichens) in which two different organisms live together in mutual benefit
the science of classification; the systematic process of arranging organisms into groups based upon structural similarities
vascular-any plant with vascular tissue; a member of the phylum Tracheophyta

nonvascular-any plants of the phylum (division) Thallophyta, characterized by a lack of vascular tissue
vascular and nonvascular plants
