  1. endosperm
    is the tissue produced inside the seeds of most flowering plants around the time of fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. This makes endosperm an important source of nutrition in human diet.
  2. cotyledon
    is a significant part of the embryo within the seed of a plant. Upon germination, the cotyledon may become the embryonic first leaves of a seedling. The number of cotyledons present is one characteristic used by botanists to classify the flowering plants (angiosperms). Species with one cotyledon are called monocotyledonous ("monocots"). Plants with two embryonic leaves are termed dicotyledonous ("dicots") and placed in the class Magnoliopsida.
  3. bean stuff
    Epicotyl (will become the shoot-stems and leaves)Radicle (embryonic root)Hypocotyl (connection between cotyledon and radicle)Cotyledon (seed leaf)Note: If the seed has one cotyledon, it is a monocot. Corn is a monocot. If it has two, it is a dicot. A bean is a dicot.
