  • Sexual Reproduction
    need two parents
  • Asexual reproduction
    only needs one parent creates genetically identical offspring
  • Binary fission
    form of asexual reproduction in which an organism divides in two
  • Budding
    new organism develops from an outgrowth of another one (Asexual)
  • Vegetative propagation
    A form of asexual reproduction
  • Runners
    long side shoots that eventually produce new plants (Asexual)
  • Leaves
    young plants on the leaves which grow into new plants if they fall off
  • Rhizomes
    underground stems that develop into new plants
  • Suckers
    new stem grows from the base of an old one
  • Bulb
    lateral buds which may grow into new plants
  • Tuber
    swollen underground stems which grow into new plants
  • Corm
    one or more internodes with at least one growing point
  • Grafting
    plant attached to base of another plant
  • Stock
    the plant onto which another plant will be attached
  • Cuttings
    stem is cut from a plant and replanted
  • Tissue culture
    The growth of a new plant in a cultured medium
  • Regular
    plant may be cut longitudinally in any plane to give two halves
  • Calyx
    made up of four sepals
  • Stamen
    male reproductive structure
  • Anther
    holds pollen
  • Filament
    holds up the anther
  • Pistil
    female reproductive structure
  • Style
    passage for the pollen tube
  • Stigma
    sticky landing place for pollen
  • Bilocular
    refers to the two chambered ovary
  • Pollination
    the transfer of pollen grains from the anther to the stigma of a flower
  • Self
    fertilization - pollination occurs between flowers of the same plant
  • Cross
    pollination - pollination between flowers of different plants
  • Coevolution
    mutual evolutionary influence between two species
  • Cotyledons
    reserve food storage
  • Spermophytes
    all seed bearing plants
  • Seedbank
    stores seeds to preserve genetic diversity
  • Polyploidy
    common technique to overcome sterility
