FLOWERS, FLOWER TYPES, FRUITS AND SEEDS
FLOWER MORPHOLOGY
flower - the reproductive organ of higher plants (e.g. angiosperms or flowering plants),
               which contains at least 1 female reproductive part, the pistil, and/or 1 male 
               reproductive part, the stamen.
    Flower Types
    complete- contains all floral parts, i.e. sepal, petal, stamen and pistil 

    incomplete - lacks one or more of the floral parts 

    perfect - contains both pistil and stamen (may or may not have sepal or petal) 

    imperfect - lacks either pistil or stamen (may or may not have sepal or petal)

            pistillate (female) - contains only pistil (may or may not have sepal or petal)

            staminate (male) - contains only stamen (may or may not have sepal or petal)

    sterile - both stamen and pistil are absent, or are non-functional 

    Plant Types Based on Flower Type Present
    monoecious - both staminate (male) and pistillate (female) flowers occur on the same
                           plant; ex. corn, cucumber

    dioecious - staminate (male) and pistillate (female) flowers occur on separate plants; 
                      ex. holly, persimmon, ginkgo 


FRUIT MORPHOLOGY
fruit - a ripened or matured ovary and its contents plus any accessory tissues. 

    pericarp - the fruit wall, which developed from the ovary wall 

    Composed of 3 layers:
    1) exocarp - outer layer of the pericarp 

    2) mesocarp - middle layer of the pericarp 

    3) endocarp - inner layer of the pericarp. 


SEED MORPHOLOGY
seed - a ripened or mature ovule consisting of an embryo with associated stored food 
            and covered by a testa.

testa - protective, outer most layer of seeds; commonly called seed coat.
