state and explain modification of leaf observed in ginger
Answers
Answer:
Onion is a bulb which is formed by the overlapping of many nodes in the condensed stem. There are fleshy and scaly leaves which are attached to the thickened base. Sweet potato and carrot are the modified form of root. Ginger is the rhizome which is a modified stem.
Explanation:
Like leaves and roots, shoots and stems also have modifications. Some examples are rhizomes, stolons, tubers, bulbs, corms, thorns, spines, cladophylls, and stem traps. Rhizomes (example: ginger, Zingiber) are underground stems that burrow into the ground just below the soil surface, and usually tend to have small, scale-like leaves that are not photosynthetic. Buds from the axils of the leaves make new branches that will grow to become aboveground shoots.
, spines (from stipules) and thorns (from Charles-Dominique et al., 2016).
Cladophylls (examples: Christmas cactus, Schlumbergera; ribbon plant, Homalocladium) are leaf-like, flattened shoots. Phyllodes are actually leaf modifications (example: Australian acacias, Acacia) they visually similar to cladophylls but originated from flattened leaf petioles. Shoot insect traps are used by some carnivorous plants, such as bladderwort (Utricularia). The following table emphasizes the diversity of organ modification.
