  1. CRCT Vocabulary ReviewUnits 1-6

  2. Round One- Unit One Cell Scientific Method Asexual reproduction Hypothesis DNA Controlled Experiment Variable Classification Homeostasis Taxonomy Dichotomous Key Bacteria Binary Fission Diffusion Osmosis Prokaryotic cell Theory

  3. Give the word that goes with each definition

  4. ________________- Tool scientist use to identify an unknown organism. Dichotomous Key

  5. ________________- Genetic material found in all living organisms that acts as the blue print of life. DNA

  6. ________________-The diffusion of water molecules from an area of high concentration to an area of low concentration. Osmosis

  7. Binary Fission _______________- Type of asexual reproduction in which a unicellular organism undergoes cell division to make genetically identical unicellular offspring.

  8. Taxonomy _______________-The science of classifying organisms and giving each a scientific name.

  9. _______________- Reproduction that produces genetically identical offspring from only one parent. Asexual Reproduction

  10. Homeostasis _______________- the maintenance of a stable internal environment.

  11. Theory _______________- A hypothesis that has been supported by lots of experimentation and tests.

  12. Hypothesis _______________- An educated guess to a scientific problem.

  13. Bacteria _______________- Among the oldest organisms on earth, these unicellular organisms have no nucleus in their cells.

  14. Prokaryotic Cell _______________- A cell that contains no membrane-bound organelles and no nuclei.

  15. Cell _______________-Membrane covered structure that contains all the materials necessary for life. Basic unit of life.

  16. Diffusion _______________-The movement of molecules from an area of high concentration to an area of low concentration.

  17. Scientific Method ______________- The steps a scientist take when conducting a controlled experiment.

  18. Variable ____________- any factor in an experiment that changes.

  19. Now it is time to shorten up these definitions….I will give you two or three words and you give me the vocabulary term.
