  1. 6. The single factor that is changed in the experiment
  2. 9. One of the two different types of cells, generally larger than prokaryotic cells, contains a variety of other organelles - nucleus
  3. 10. Organs united by an overall function
  4. 13. The six major subdivisions of the domains. (Eubacteria, Archaea, Protista, Fungi, Plantae, and Animalia)
  5. 14. Many-celled**
  6. 17. Small cells that don’t have a nucleus. Usually only 1-2 micrometers and don’t have membrane bound organelles
  7. 18. Cells that combine become tissue in multicellular organisms and when tissue combine, organs are formed
  8. 19. Structures, physiological processes, or behaviors that aid in survival or reproduction in a particular environment
  9. 22. Name for the different groups organisms can be put into.
  10. 24. Organisms of the same type that are capable of breeding with one another
  11. 25. The diversity of species in a region and interactions that sustain them
  12. 28. A substance that can neither be broken down nor converted to different substances by ordinary chemical means.
  13. 30. An explanation that is thought out and produced by using the scientific method
  14. 32. water, glucose, DNA
  15. 34. The act of knowing or recording something using your senses.
  16. 35. A single celled organism. Unlike a multicellular, they are only consisted of one singular cell
  17. 38. Principle that implies that all events can be traced to natural causes that are potentially within our ability to comprehend
  18. 39. The maintenance of fairly constant conditions within an organism’s body. This includes things like temperature and balance of fluids.
  19. 43. Process that plants and some unicellular organisms use to store energy by capturing the energy of the sunlight directly and storing it in energy-rich molecules like sugars
  20. 44. All the variables not being tested remain constant and are then compared with the experimental situation
  21. 45. A thin casing around the cytoplasm of the cell
  22. 47. A living thing made up of one or more cells and able to carry on the activities of life.
  23. 50. Complex models that have a framework of carbon that has some hydrogen bond
  24. 53. A statement based on experimental measurements and observations
  25. 54. Organisms that cannot photosynthesize such as fungi or animals that acquire energy prepackaged into the molecules of other bodies of other organisms
  26. 55. A procedure carried out under controlled conditions in order to discover an unknown effect or law, to test or establish a hypothesis

  1. 1. This theory states that the cell is the basic unit of life.
  2. 2. A group of individuals of the same species living and interbreeding within a given area
  3. 3. A group of six interrelated operations, observation, question, hypothesis, experiment, analysis and conclusion
  4. 4. The ability to do work, such as carrying
  5. 5. Something you say or write in order to ask or wonder something
  6. 7. A system for naming species. Each organism is assigned a genus and a species. The genus is always capitalized but the species name is not
  7. 8. Small structures specialized to carry out specific functions such as moving the cell, obtaining energy or synthesizing large molecules.
  8. 11. A membrane-enclosed sac containing the cell’s genetic material and controls the activities of the cell
  9. 12. Process by which organisms with specific traits that help them cope with the rigors of their environment reproduce more successfully than others that lack these traits
