plumule

Examples of plumule in the following topics:

• Development of the Seed

  • The embryonic axis consists of three parts: the plumule, the radicle, and the hypocotyl.
  • Upon germination in dicot seeds, the epicotyl is shaped like a hook with the plumule pointing downwards; this plumule hook persists as long as germination proceeds in the dark.
  • Therefore, as the epicotyl pushes through the tough and abrasive soil, the plumule is protected from damage.
  • Both monocot and dicot embryos have a plumule that forms the leaves, a hypocotyl that forms the stem, and a radicle that forms the root.
  • The embryonic axis comprises everything between the plumule and the radicle, not including the cotyledon(s).
