Across
  1. 2. a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living
  2. 5. a simple sugar produced by photosynthesis
  3. 9. the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
  4. 10. an organism that makes its own food
  5. 13. a tiny cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
  6. 18. any of the tiny pores in the epidermis of the leaf or stem of a plant forming a slit of variable width that allows movement of gasses in and out of the cell
  7. 19. when a cell consumes oxygen and glucose to produce energy it can use
  8. 20. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
  9. 21. the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
  10. 22. the natural coloring matter of animal or plant tissue
  11. 23. the material of which the chromosomes of organisms other than bacteria are composed. It consists of protein, RNA, and DNA.
  12. 24. the gas produced by photosynthesis
  13. 25. the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.Metaphase
Down
  1. 1. the stage of cell division in which the chromosomes move away from one another to opposite poles of the spindle.
  2. 3. required whit carbon dioxide to produce oxygen by photosynthesis
  3. 4. cell division in ordinary tissue growth
  4. 6. cellular goo
  5. 7. organelle which converts oxygen and nutrients into ATP
  6. 8. these are protein structures that pull apart the genetic material in a cell when the cell divides.
  7. 11. a highly regulated membrane barrier that separates the nucleus from the cytoplasm
  8. 12. the process by which a cell captures energy in sunlight and uses it to make food
  9. 13. the gas used by plants in photosynthesis
  10. 14. an organism that cannot make its own food
  11. 15. each of a pair of curved cells that surround a stoma becoming larger or smaller according to the pressure in the cell
  12. 16. the region of a chromosome to which the microtubules of the spindle attach, via the kinetochore, during cell division.
  13. 17. e green pigment present in all green plants and in cyanobacteria responsible for the absorption of light to provide energy for photosynthesis
  14. 19. a plastid that contains chlorophyll and in which photosynthesis takes place
