  12. 27. respiration- A chemical reaction that does not require the presence of oxygen
  13. 28. membrane- controls what goes in and out of the cell
Down
  1. 1. - the phases of th cell cycle when a cell grow doubles the DNA
  2. 2. a molecule that carries genetic information in cells and viruses
  3. 4. breaks down waste materials within the cells
  4. 5. division process in which DNA of cell nucelcus is split into two set of chromosomes
  5. 6. What the body does to maintain the same or balances
  6. 7. where MRNA is read by ribosomes to assemble amino acids into protein
  7. 9. tree- a diagram that shows relationships among organisms
  8. 11. transport- movement of molecules across a cell membrane against the concentration gradient
  9. 12. a molecule it's like a book of code that tells your cells what to do
  10. 17. only plant and animal cells
  11. 18. a diagram used to predict gnotypes and phenotypes of offspring
  12. 19. traps light energy found in chloroplasts makes plants green
  13. 20. diffusion- movement of large or uncharaged molecules molecules across a cell membrane using a protein channel
  14. 21. bond- pairs of nitrogen bases held together by twoProtein synthesis synthsis- which creates new proteins
  15. 22. respiration- A chemical reaction that requires the presence of oxygen
  16. 26. movement of water across a semi-premeable membranes
