Enlarged approximately eight times, this model allows students to easily study the floral components and the reproductive functions of flowers. Model can be disassembled to reveal the pollen grains inside, showing the process of pollination. Important structures are numbered on the flower model and corresponds to an identification key. Structures include receptacle, petal, sepal (all sepals combined are the calyx), gynoecium (stigma and style), male stamen (anther and filament), pollen, pollen tube, embryo sac, antipodals, polar nuclei, and egg cell and synergids. 17-11/16 in. x 15-11/16 in. x 12 in.
