Soybean and Bees

Primordium: Derived from Latin primordium: the first, the beginning.
Prophylls: A plant structure resembling a leaf (as a bracteole) or consisting of a modified or
rudimentary leaf (as a foliar primordium).
Protoderm: A plant tissue formed by the apical meristem of shoots and roots that subsequently
gives rise to the epidermis.
Puberulent: Of a leaf, stem, etc. slightly downy with very short hairs; minutely pubescent
Ribosome: A complex molecular machine found within all living cells that serves as the site
of biological protein synthesis (translation). Ribosomes link amino acids together in the order
specified by messenger RNA (mRNA) molecules.
Sporangia: An enclosure in which spores are formed. It can be composed of a single cell or
can be multicellular. All plants, fungi, and many other lineages form sporangia at some point
in their life cycle. Sporangia can produce spores by mitosis, but in nearly all land plants and
many fungi, sporangia are the site of meiosis and produce genetically distinct haploid spores.
Sporogenous: An elongated, spirally thickened, water-attracting cell in the capsule of a liverwort,
derived from sporogenous tissue and assisting in spore dispersal.
Sporopollenin: A major component of the tough outer (exine) walls of plant spores and pollen
grains
Stamen: The male reproductive organ of plants.
Staminal sheath: A protection coating of the stamens.
Staminal tube: Filaments of the stamens united so as to form a tube.
Style: An elongated part of a carpel, or group of fused carpels, between the ovary and the
stigma.
Suspensor: The chain of cells that anchors a plant embryo in the surrounding gametophyte
tissue. In flowering plants, the suspensor attaches the embryo to the embryo sac and extends
to push the embryo into the endosperm.
