What Is the Stem Modification Chart Used For?
A stem is recognised by its nodes, internodes and buds, and these features remain even when the stem looks nothing like a typical shoot. Underground stems store food and help the plant survive bad seasons: the potato tuber, whose “eyes” are buds at the nodes; the rhizome of ginger and turmeric; the corm of Colocasia; and the bulb of onion, where the stem is reduced to a small disc beneath fleshy leaves. Above ground, stem tendrils help gourds and grapevines climb, axillary buds become protective thorns in Bougainvillea and citrus, and flattened green stems take over photosynthesis in cacti such as Opuntia. Runners, stolons, offsets and suckers, as in grasses, mint, water hyacinth and banana, spread the plant and give rise to new plants. The topic belongs to the class 11 chapter on the morphology of flowering plants and to college botany practicals.
A useful exercise is to bring a potato, a piece of ginger, an onion and a twig of Bougainvillea into the lab and ask students to find the nodes and buds that prove each one is a stem, using the chart as the reference. The laminated sheet wipes clean and rolls up on its rollers. The listing does not say which examples the artwork uses, so ask JLab for a larger image if you need to match it to your syllabus.

Frequently Asked Questions
What is the Stem Modification Chart used for?
It is used to teach the modified stems of flowering plants — underground, sub-aerial and aerial types — in class 11 biology and college botany. The listing does not detail the artwork; see the photograph on this page or ask JLab for a larger image.
What size and finish does it have?
It is 58 x 90 cm, about 22.8 x 35.4 inches, printed in full colour on art paper, laminated on both sides with thick plastic film and fitted with plastic rollers.
Why is a potato a stem but a sweet potato a root?
A potato tuber has nodes, seen as “eyes”, each with buds that can sprout into new shoots, so it is a swollen underground stem. A sweet potato has no nodes or buds of that kind and develops from the roots, so it is a modified root that stores food.
Is onion a stem or a leaf?
Both parts are present. The onion bulb has a very short, disc-shaped stem at its base; the fleshy layers we eat are leaf bases that store food around it.
What is the minimum order and dispatch time?
The minimum order is 10 units, with each chart supplied singly and visually inspected. Dispatch is usually within 7–10 working days; export shipments need extra transit time.
