Root Growth Cone Model in Two Cross-Sections

Root Growth Cone Model in Two Cross-Sections

A 3D model made from colored plastic, mounted on a base. It presents a fragment of a root with a growth cone, shown in two cross-sections — longitudinal and transverse. Visible elements include: root hairs, epidermis (epiblema), primary cortex, exodermis, intercellular spaces, endodermis, starch grains, pericycle (okolnica), proto- and metaxylem, phloem, xylem, and spiral and ring thickenings. Overall dimensions of the teaching aid: 41 x 21.5 x 12.5 cm.
