Question Answer
What is life? 1. All life forms contain deoxyribonucleic acid, which is called DNA. 2. All life forms have a method by which they extract energy from their surroundings and convert it into energy that sustains them. 3. All life forms can sense changes in their surroundings and convert it into energy that sustains them. 4. All life forms reproduce
Metabolism The sum total of all processes in an organism which convert energy and matter from outside sources and use that energy and matter it to sustain the organisms life functions.
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 its 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 environment
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 difference in the DNA of an organism compared to 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 random chemical reactions.
Prokaryotic cell A cell that has no distinct, membrane-bound organelles
Eukaryotic cell A cell with distinct, membrane-bound organelles
Species A unit of one or more populations of individuals that can reproduce under normal conditions, produce fertile offspring, and are reproductively isolated from other such units.
Taxonomy The science of classifying organisms
Binomial nomenclature Naming an organism with its genus and species name
Three-Domain System Domains Archaea, Bacteria, Eukarya
Archaea Prokayotic organisms that live in extreme enviroments
Bacteria The other prokaryotic organisms in creation
Eukarya All organisms with Eukarytic Cells
