Across
  1. 3. type of sugar
  2. 7. a series of chemical reactions in some organisms that uses light energy and makes food
  3. 8. eukaryotic cell containing only one chromosome from each homologous pair
  4. 9. haploid reproductive cell produced by female reproductive organs
  5. 12. a region near the middle of each chromatid that holds together the sister chromatids
  6. 13. a cell that is the source of other cells, cell that divides to produce two or more daughter cells
  7. 14. a copy of a chromosome made during S-phase of cell cycle
  8. 15. a mature sexual reproductive cell that unites with another cell to form a new organism; haploid
  9. 18. life cycle of a cell that includes phases of growth and development and reproduction
  10. 19. a pigment found in plants that reflects green light
  11. 20. a process that releases energy from glucose and creates lactic acid
  12. 27. a stage in interphase in which the cell grows and replicates the cell's chromosomes
  13. 29. adenosine triphosphate or molecules of usable cellular energy
  14. 30. the first phase of a mitosis in which the DNA that makes up a replicated chromosome twists into tight coils
  15. 31. a chemical process that releases energy from food molecules;it begins and ends in the cytoplasm and does not involve mitochondria or use of oxygen
  16. 32. fusion of a sperm cell with an egg cell to produce a zygote
  17. 33. the division of a cell and its nucleus that produces haploid daughter cells
  18. 34. the phase of a cell cycle in which a cell is preparing to reproduce
  19. 35. the final phase of mitosis, in which a new membrane forms around each set of chromosomes, creating two identical nuclei
  20. 36. the second stage of mitosis in which the replicated chromosomes move to the middle of the cell and the pairs of sister chromatids line up end to end across the center of the cell
Down
  1. 1. diploid cell formed by the fusion of one egg and one sperm cell; develops into a new organism
  2. 2. a pair of similar chromosome
  3. 4. fibers that attach to the centromeres and helps pull the chromosomes apart in mitosis and meiosis
  4. 5. organelle that uses light energy to make food from water and carbon dioxide
  5. 6. a form of reproduction; combining genetic material in two different cells; producing an offspring
  6. 10. a stage in interphase in which the cell grows and carries out its usual functions
  7. 11. two cells that form when the cytoplasm and its components divide
  8. 15. a stage in interphase in which the cell grows and replicates organelles
  9. 16. the first step of cellular respiration that occurs in a cell's cytoplasm
  10. 17. haploid reproductive cell produced by the male reproductive organs
  11. 18. a disk formed between the two new nuclei of a plant cell that is dividing
  12. 21. a series of chemical reactions that transforms the energy in food molecules to usable cellular energy
  13. 22. the final stage of cell division when the cytoplasm of the cell divides
  14. 23. a eukaryotic cell that contains a complete set of homologous chromosome pairs
  15. 24. a process in which the nucleus of the cell divides
  16. 25. a process that releases energy from glucose and creates ethanol
  17. 26. organelle that transforms the usable energy in food molecules
  18. 28. the third phase stage of mitosis, in which the sister chromatids of each replicated chromosome begin to separate
