Collenchyma
Collenchyma (Product Code: SCL481/159) is a prepared slide of collenchyma, the living supporting tissue that keeps young stems, petioles and leaf midribs firm while they grow, used in plant tissue lessons. Students examine it to learn how uneven wall thickening provides strength without stopping growth, and teachers use it to bridge parenchyma and sclerenchyma; it is clear borosilicate glass in a white rectangular plastic box. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for school and college botany labs.

What Is the Collenchyma Slide Used For?
Collenchyma cells are alive at maturity, and their walls are thickened with cellulose and pectin, most often at the corners where several cells meet (angular collenchyma). Under high power the thickened corners look bright and glassy, while the rest of the wall stays thin and intercellular spaces are few. In dicot stems this tissue usually lies just below the epidermis as a hypodermis, which is why it is often studied alongside a dicot stem section.
When schools assemble a microscope slides set for plant tissues, collenchyma is the slide that explains how a herbaceous stem can bend in the wind without snapping. A useful task is to ask students to draw three adjacent cells and shade only the thickened corners. After use, lift the slide from the stage without sliding it across the clips and return it to its box.

Frequently Asked Questions
Where is collenchyma found in a plant?
Collenchyma occurs mainly beneath the epidermis of young dicot stems, in petioles and along leaf midribs, and is generally absent from roots and most monocot stems. The Collenchyma slide helps students recognise it before they look for it in whole stem sections.
How do I recognise collenchyma on the Collenchyma slide?
On the Collenchyma slide, look for living cells whose walls are noticeably thicker at the corners, with a shiny, glassy appearance and very few spaces between cells. Compare them with the thin, even walls on a parenchyma slide.
Why do growing organs use collenchyma rather than sclerenchyma?
Collenchyma walls can still stretch, so the tissue supports a stem or petiole while it lengthens, whereas lignified sclerenchyma would stop that growth. The Collenchyma slide and a sclerenchyma slide viewed together make this contrast easy to explain.
Is the Collenchyma slide a permanent mount?
Our listing for the Collenchyma slide does not describe the mounting method; it states only the clear borosilicate glass slide and the white plastic box. Please ask through our contact page and we will tell you what we can confirm before you order.
Who supplies the Collenchyma slide?
The Collenchyma slide is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India, to schools, colleges and distributors in India and international markets, along with the other simple-tissue slides.
Can you quote the Collenchyma slide for a whole class?
Yes. Share the product code SCL481/159 and the number of students or workstations, and we will prepare an institutional quotation for the Collenchyma slide, adding the parenchyma and sclerenchyma slides if you want the full series.
