Dicot Stem Model, Three Dimensional, Transverse and Longitudinal Section View

The detailed 3D rendering of a dicot stem section, with both transverse and longitudinal views, is ideal for studying the structure and function of a dicot stem. Key features are colored and numbered for comparison with the key that is included. This model provides a visually and kinesthetically effective method for studying the structure and function of the various structures of a dicot stem. The model is mounted on a sturdy ABS plastic base for display.

Details Identified: cuticle, epidermis, hypoepidermis, middle cortex, endodermis, oil duct, pericycle, phloem, cambium, meta and proto xylem, xylem parenchyma, medullary ray, and pith.

Cuticle: A waxy layer on the outer surface of the epidermis, providing protection and reducing water loss.

Epidermis: The outermost layer of cells, providing a protective barrier.

Hypoepidermis: A layer beneath the epidermis, sometimes consisting of sclerenchyma cells for support.

Middle cortex: The region between the epidermis and the vascular tissue, often containing parenchyma cells for storage and support.

Endodermis: A layer surrounding the vascular tissue, regulating the movement of substances.

Oil duct: A specialized structure for storing and secreting oils.

Pericycle: A layer of cells within the vascular cylinder, often involved in the formation of lateral roots and secondary growth.

Phloem: Vascular tissue responsible for transporting sugars and other organic compounds throughout the plant.

Cambium: A layer of meristematic tissue (vascular cambium) that produces new xylem and phloem cells, contributing to secondary growth.

Meta and Proto xylem: Different types of xylem, with metaxylem developing later than protoxylem and typically having wider vessels.

Xylem parenchyma: Living cells within the xylem tissue, involved in storage and other functions.

Medullary ray: Cells extending radially from the pith to the cortex, facilitating lateral transport.

Pith: The central region of the stem, composed of parenchyma cells, often involved in storage.

Educational Use: The model is designed for use in medical anatomy and physiology courses, patient education, and in medical offices where visualization of the female pelvis is needed.

Quality Construction: It is crafted by subject matter experts and features vibrant, hand-painted details with eco-friendly paint.
