Giant Dicot Flower Model - Student Edition

Brand: Denoyer Geppert
 
Students explore this greatly enlarged, unbreakable vinyl model, discover the arrangement of floral components, and the reproductive function of flowers. Since the petals, sepals, and stamens are
detachable, students can begin the investigation with the model disassembled and build 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 tip of this tube are two sperm nuclei - one of which is destined to unite with the egg to form the embryo - 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. Floral structures are number-coded for identification in the key which accompanies the model.
Overall dimensions: 17 in. x 14 in. x 10 in.
