Investigating the Classification of Organisms/Animals
annelids – bilaterally symmetrical worms; have round, segmented bodies; terrestrial and aquatic species; includes earthworms, leeches, and marine polychaetes
Archaea – all organisms in this domain are unicellular and prokaryotic; they have a chemically different cell wall/cell membranes and unique genetics from Domain Bacteria
arthopods – largest animal group; have hard exoskeletons, segmented bodies, and pairs of jointed appendages; land and aquatic species; includes insects, crustaceans, and spiders
Bacteria – all organisms in this domain are unicellular and prokaryotic; they have a strong exterior cell wall and a cell membrane composed much like Eukarya cell membranes
binomial nomenclature – two-word naming system developed by Carolus Linnaeus
chordates – organisms with internal skeletons and specialized body systems; most have paired appendages; all at some time have a notochord, nerve cord, gill slits, and a postanal tail; include fish, amphibians, reptiles, birds, and mammals
class – third-highest taxonomic category, below phylum (animals) or division (plant)
classify – to group ideas, objects, or information based on similarities
cnidarians – radially symmetrical organisms; have a digestive cavity with one opening; most have tentacles armed with stinging cells; live in aquatic environments singly or in colonies; includes jellyfish, corals, hydra, and sea anemones
domain – one of the three broadest categories of organisms; based on cell type and rRNA analysis
division – second-highest taxonomic category in the plant and fungi kingdoms (in the animal kingdom, phylum replaces division)
echinorderms – marine organisms; have spiny or leathery skin and a water-vascular system with tube feet; are radially symmetrical; includes sea stars, sand dollars, and sea urchins
Eukarya – all organisms in this domain have eukaryotic cells possessing membrane-bound organelles
family – the fifth-highest taxonomic category, below an order
genus – a group of similar organisms
kingdom – first and largest category in the scientific classification system or organisms; can be divided into smaller groups: phylum, class, order, family, genus, and species of the taxonomic categories
mollusks – soft-bodies animals, many with a hard shell and soft foot or foot-like appendage; a mantle covers the soft body; aquatic and terrestrial species; includes clams, snails, squid, and octopuses
order – the fourth-highest taxonomic category, below a class
species – smallest, most precise classification category
species diversity – variety of plants, animals, and other organisms
Investigating Photosynthesis/Plants
angiosperm – plant that produces flowers and seeds in fruits; examples include apple trees, squash, roses, grasses, oak trees, etc.
carbon dioxide - A colorless, odorless, incombustible gas formed during respiration, combustion, and organic decomposition
chlorophyll – a chemical in chloroplasts that can absorb or trap light energy
chloroplast – organelle in which photosynthesis takes place
ferns-vascular plants that use spores to reproduce; ferns are also characterized by leaves called fronds
food – material, usually of plant or animal origin, that contains or consists of essential body nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals, and is ingested and assimilated by an organism to produce energy, stimulate growth, and maintain life
nonvascular plant – plant group containing mosses and liverworts
gymnosperm – vascular plant that produces “naked seeds”-seeds that do not have protective coverings, examples include ginkgo trees, cycads and conifers (pines, cedars, and junipers)
organelle – A differentiated structure within a cell, such as a mitochondrion, vacuole, or chloroplast, that performs a specific function
oxygen - a colorless tasteless odorless gaseous element that constitutes 21 percent of the atmosphere and is found in water, in most rocks and minerals, and in numerous organic compounds
photosynthesis – using light to make glucose and oxygen
producers – organisms that make their own food (chemical energy)
vascular plant – plant containing vascular tissue
vascular tissue – long, tube like cells in which water and nutrients are transported through the plant
annelids – bilaterally symmetrical worms; have round, segmented bodies; terrestrial and aquatic species; includes earthworms, leeches, and marine polychaetes
