A large and highly detailed model of a cross-section of plant stem with a dicot (dicotyledon) structure. The dicot stem structure differentiates itself with two embryonic leaves or cotyledons, as opposed to the monocot structure, which possesses only one. This model also clearly shows the epidermis, cork layer, phloem region, cambium xylem region, pith, and other vital structures.
A great addition to a bio lab or classroom, and an innovative way to get kids interested the biology of plants and plant structure.
