Pumpkin stem microscope slide, 100% Clarity of 5 Dicot Vascular Zones

Our Pumpkin Stem slides are professionally prepared to highlight the bicollateral vascular bundles typical of the Cucurbitaceae family. This specimen is a 5-star choice for demonstrating the transport systems of higher plants in both secondary and collegiate biology labs.

Elite Product Specifications:

Standard Dimensions: 25.4mm x 76.2mm (1″ x 3″).
Staining: Professionally stained to provide 100% color contrast between the lignified xylem (red/orange) and the nutrient-transporting phloem (blue/green).
Optical Quality: High-transparency glass ensures zero distortion when observing large vascular structures at 40x to 400x magnification.

5 Essential Anatomical Highlights:

Large Bicollateral Vascular Bundles: A unique feature where phloem is located on both the outer and inner sides of the xylem. * Sieve Tubes & Companion Cells: 100% visible under high power, allowing for the study of specialized phloem cells.
Hollow Pith: The center of the stem features a large, clear lacuna (cavity) formed during growth, a hallmark of the pumpkin family.
Epidermis & Hypodermis: The outer protective layer, often featuring multicellular trichomes (hairs) and collenchyma for mechanical support.
Xylem Vessels: Large, thick-walled cells responsible for 100% of the plant’s upward water transport.

Biological Significance:

Efficient Transport: The bicollateral arrangement provides an advanced model for understanding how plants move sugars through the phloem.
Structural Adaptation: The combination of a hollow pith and peripheral mechanical tissues demonstrates how plants achieve height and strength with minimal biomass.
Dicot Identification: Serves as a perfect comparison specimen when studied alongside monocot stems like corn or wheat.

Key Terminology for Microscope Slides

To help you select the most suitable specimen for your research or teaching, please refer to our standard sectioning abbreviations:

W.M. (Whole Mount): The entire organism or structure is preserved and mounted on the slide.
C.S. (Cross Section): A thin transverse section through the organism or tissue plane.
L.S. (Longitudinal Section): A vertical section along the longest plane of the organism.
C.S. & L.S.: Both Cross and Longitudinal sections are mounted on the same slide for side-by-side comparison.
