Flower Dicot Models |
|
 |
As students explore this greatly enlarged,
unbreakable vinyl model, they’ll 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" x 14" x
10". |

Model of Monocotyledon |
|
 |
This model of corn gives details of cellular
anatomy of the generalized monocot in cross and longitudinal section.
Shows important structures such as cuticular layer, epidermis,
thick-walled mechanical tissue, fundamental parenchymatous tissue, and the
details of closed vascular bundles. Enlarged 45 times. Made of plastic and
mounted on a wooden base. Key included. Dimensions: 42 cm x 43 cm x 15 cm |

| Leaf
Structure Model |
|
 |
Magnified 45 times from a lima bean leaf.
This model vividly shows the transverse and longitudinal sections, as well
as the upper and lower surfaces of a typical leaf. The mesophyll includes
palisade parenchyma and spongy parenchyma. Both surfaces are shown with
stomas and guard cells. Also shown is the detail of vascular bundles, such
as xylem, phloem, and the veins. Complete with key. Plastic construction.
