Anabolism The sum total of all processes in an organism which use energy and simple chemical building blocks to produce large chemicals and structures necessary for life.
Catabolism The sum total of all processes in an organism which break down chemicals to produce energy and simple chemical building blocks.
Photosynthesis The process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food.
Herbivores Organisms that eat only plants.
Carnivores Organisms that eat only organisms other than plants.
Omnivores Organisms that eat both plants and other organisms.
Producers Organisms that produce their own food.
Consumers Organisms that eat living producers and/or other consumers for food.
Decomposers Organisms that break down the dead remains of other organisms.
Autotrophs Organisms that are able to make their own food.
Heterotrophs Organisms that depend on other organisms for their food.
Receptors Special structures that allow living organisms to sense the conditions of their internal or external enviroment.
Asexual reproduction Reproduction accomplished by a single organism.
Sexual reproduction Reproduction that requires two organisms.
Inheritance The process by which physical and biological characteristics are transmitted from the parent (or parents)to the offspring.
Mutation An abrupt and marked change in the DNA of an organism compared to that of its parents.
hypothesis An educated guess that attempts to explain an observation or answer a question.
Theory A hypothesis that has been tested with a significant amount of data.
Scientific Law A theory that has been tested by and is consistent with generations of data.
Microorganisms Living creatures that are too small to see with the naked eye.
Abiogenesis The idea that long ago, very simple life forms spontaneously appeared through chemical reactions.
Biological classification system Kingdom, Phylum, Class, Order, Family, Genus, Species. Help you remember King Philip Cried Out, "For Goodness Sake!"
Prokaryotic Cell A cell that has no distinct membrane-bounded organelles. These cells do not contain internal structures to perform specific tasks.
Eukaryotic cell A cell with distinct, membrane-bounded organelles. These cells contain internal structures to perform specific tasks.
Kingdom (Monera) contains all organisms that are comosed of either one prokaryotic cell or simple association of prokaryotic cell. Sample: Blue-green algae and bacteria
Kingdom (Protista) Organisms that are composed of only one eukaryotic cell or a simple association of eukaryotic cells. Sample: Amoebae, paramecia and algae Bothe Monera and Protista make up the vast majority of life on earth.
Kingdom (Plantae) composed mostly of autotrophs-organisms that produce their own food. Sample: multicelled organisms with eukaryoticcells. Sample: plant-trees, grass, flowering bushes, etc.
Kingdom (Animalia) Contains multicellular organisms with eukaryotic cells-they are different from Kingdom Plantae because they are heterotrophs-depend on other organisms for food but are not decomposers. Sample: animals-grasshoppers,birds, cats, fish, snakes, etc.
Species A unit of one or more populations of individuals that can reproduce under normal conditions, produce fertile offspring, and are rproductively isolated from other such units.
Taxonomy The science of classifying organisms.
Binomial nomeclature Naming an organism with its genus and species name.
Carrolus Linnaeus The person who developed the classification system called the five-kingdom system in the 1700's.
Three-domain system Classifies all living things into one of three large domains: Archaea, Bacteria, and Euarya.
Eukarya domain Contains all organisms with eukaryotic cells. Which in the 5 kingdom system would include: Protista, fungi, plantae, and Animalia.
Archae domain The prokaryotic organisms that live in very extremem enviroments -boiling hot springs, salty lakes.
Bacteria domain prokaryotic organisms that live in more normal enviroments.
Metabolism The sum total of all processes in an organism which convert energy and matter from outside sources and use that energy and matter to sustain the organism's life functions.
Spontaneous generation A hypothesis that life forms originate from nonliving things.
Organelles Distinct structures within a eukaryotic cell which are necessary to perform individual tasks to complete the functions of life.
First criteria for life All life forms contain deoxyribonucleic acid, which is called DNA.
Second criteria for life All life forms have a method by which they extract energy from the surroundings and convert it into energy that sustains them.
Third criteria for life All life forms can sense changes in their surroundings and respond to those changes.
Forth criteria for life All life forms reproduce.
