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

Our Rhizobium japonicum slides feature high-quality sections of legume root nodules, professionally stained to highlight the presence of “bacteroids” within the plant host cells. This slide is an essential tool for botany, microbiology, and environmental science curricula.

Product Specifications:

Dimensions: 25.4mm x 76.2mm (1″ x 3″)
Staining: Professionally double-stained (likely Safranin and Fast Green). The plant cell walls appear red or purple, while the dense clusters of bacteria within the cells appear blue or green.
Quality Control: Each section is selected to show a clear connection between the nodule and the primary root vascular system.

Key Biological Features:

Infected Zone: The large, dark-staining central region of the nodule. This area is packed with plant cells containing thousands of bacteroids (the specialized form of Rhizobium that performs nitrogen fixation).
Nodule Cortex: The protective outer layers of the nodule that regulate oxygen levels, ensuring the nitrogenase enzyme can function properly.
Vascular Connection: Observe the vascular bundles extending from the main root into the nodule. These transport sugars from the plant to the bacteria and carry fixed nitrogen (as amides or ureides) back to the plant.
Host Cell Hypertrophy: Note how the infected plant cells are significantly larger than the surrounding uninfected cortical cells.

Biological Significance:

Nitrogen Fixation: Rhizobium japonicum converts atmospheric nitrogen ( $N_2$ ) into ammonia ( $NH_3$ ), a form the plant can use for growth.
Symbiotic Mutualism: The plant provides the bacteria with carbohydrates and a protected environment, while the bacteria provide the plant with essential nutrients.
Agricultural Impact: Understanding this relationship is key to sustainable farming, as it reduces the need for synthetic nitrogen fertilizers.

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.
