What is Life?

" Don't try this at home! "

Biology - The study of living things.

Movement - Respond to stimuli - Complexity (traits of living and nonliving).

*Cellular organization - All living things are organized and made of cells.

          Cell Theory - All living things are made of cells.

                    Unicellular - 1 cell

                    Multicellular - many cells

*Metabolism - All of the chemical reactions in an individual.

*Homeostasis - Ability to maintain a constant internal environment.

*Reproduce - Living things can reproduce things like themselves.

          Asexual - Individual splits in half - identical.

          Sexual - 2 parents contribute genetic information and newborn in not identical.

*Heredity - Transmission of traits (characteristics) from parents to offspring.


Evolution - Decent with modification - All organisms have a common ancestor and each one is adapted to a particular way of life.

          Natural Selection - The process by which the individuals most adapted to their environment are most likely to produce healthy offspring who in turn reproduce.

Taxonomy - The science of classifying living things into groups.

                    Monera - Bacteria (Ancient and Modern)

                    Fungi - Mold, fungus and mushrooms

                    Protista - One celled plants, animals, and fungi

                    Plantae - Multicellular plants

                    Animalia - Multicellular animals

       Kingdom - Phylum - Class - Order - Family - Genus - Species (KFCOFGS) -

Binomial nomenclature - Two name system: Genus-species names


Scientific Method - study a question or problem in a logical and organized way.

          *Observation - something you read or see or hear about (Your question)

          *Hypothesis - Best guess to explain our observation

          *Experimentation - Test our hypothesis

                    Experimental groups - Gets a treatment

                    Control group - No treatment - compare to experimental group

          *Conclusion - Was the hypothesis supported

          *Publish findings - Publish experiment in a scientific journal

          *Theory - A fact that science has been unable to disprove!
