  20. Apical meristem
    Like apex, top of plant
  21. Scarification
    Breaking seed coat. By acid, hot water, fire, or mechanical.
  22. Stratification
    Cool, moist conditions provided to seed for germination.
  23. Autotrophic
    Self-sustaining; plant converts sunlight into food.
  24. Epigeous germination
    Seed germination in which the cotyledons are raised above the soil surface.
  25. Hypogeous germination
    Seed germination in which the cotyledons remain below the soil surface.
  26. Endosperm
    Provides nutrition to embryo.... food storage tissue in seeds.... "within" "seed"
  27. Coleoptile
    Embryonic root of a monocot
  28. Plumule
    An embryonic shoot
  29. Mitochondria
    Power plants of cell. Where cell respiration provides energy. (double membraned organelle)
  30. Cellulose
    A plant substance forming a part of the structure of cell walls. Starch
  31. Mitosis
    When a cell divides to make one exactly like itself.... a cell divisional process in which the chromosomes are duplicated
  32. Testa

  34. Protoplasm
    The living substance of cells, including cytoplasm and nucleus.
  35. Osmosis
    The diffusion of water across permeable cell membranes that select for or against certain substances.
  36. A living thing has:
    1 cells. 2 metabolism. 3 growth. 4 reproduction. 5 responds to the environment.
  37. Allelopathy
    "mutual suffering" , release of chemicals by a plant to discourage the growth of other plants near it.
  38. Cellular respiration
    The chemical breakdown of food substances, resulting in the liberation of energy.
