Ricinus communis Old Stem C.S., Prepared Microscope Slide

This premium botanical slide features a mature cross-section (C.S.) of the Castor Bean (Ricinus communis) stem. It serves as an essential teaching model for demonstrating advanced secondary growth and the complex tissue organization characteristic of woody dicotyledonous plants.

Product Specifications:

Dimensions: 25.4mm x 76.2mm (1″ x 3″)
Staining: Professionally double-stained with Safranin and Fast Green for high-contrast differentiation between lignified (red) and cellulosic (green/blue) tissues.
Section Thickness: Expertly microtomed to ensure optimal light transmission and cellular clarity.
Quality Control: Each slide is individually inspected to ensure a complete, undistorted section free of air bubbles or debris.

Key Anatomical Features:

Vascular Cylinder: In this mature specimen, the discrete primary bundles have merged into a continuous ring of secondary xylem and phloem.
Secondary Xylem (Red): Observe the dense network of thick-walled vessels and tracheids responsible for both fluid transport and the mechanical “woodiness” of the stem.
Secondary Phloem (Green): Located on the outer periphery of the vascular cambium, showcasing the sieve tube elements and companion cells.
Vascular Cambium: A distinct, thin layer of meristematic cells that drives the lateral growth (girth) of the plant.
Pith & Cortex: Features a large central pith (frequently hollow in older specimens) surrounded by a supportive cortex and a protective outer epidermis.

Applications & Best Viewing:

Educational Level: University-level Botany, Plant Physiology, and Advanced High School Biology.
Magnification Guide: Start at 40x to view the overall tissue arrangement; use 100x and 400x to study cell wall thickness and cambial activity.
Comparative Study: Ideal for side-by-side comparison with monocot stems (Zea mays) to illustrate the differences in vascular organization.

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.
