This affordable model illustrates the processes of
pollination and fertilization, and separates into seven parts. The petals, sepals,
and stamens are detachable, so students can begin the investigation with the model
disassembled, and put together the flower as they learn about its parts and their
functions. One anther is sectioned open to reveal the pollen grains within.
Adhering to the stigma are six pollen grains, demonstrating the process of
pollination. One of these grains has generated a pollen tube which has entered the
ovary. Visible near the top of this tube are two sperm nuclei, one of which is
destined to unite with the egg to form the embryo while the other will fuse with the polar
nuclei to become the endosperm tissue which will nourish the developing embryo. This
process of double fertilization is unique to flowering plants.
26 number-coded floral structures are explained in detail
in the accompanying 4-page Study Guide. Overall dimensions are 17 x 14 x 10 inches
(43 x 36 x 25 cm).
