Starch is stored in the form of amylase and amylopectin sugar which is broken down to release glucose. 4 Types of modified stem. Storage Roots-These roots become fleshy and swollen due to the accumulation of food stored in roots.The modification of tap roots consists in the enormous swelling and enlargement of the primary root with slender hair like lateral or branch roots. white, or Irish, potatoes). Some examples are rhizomes, stolons, tubers, bulbs, corms, thorns, spines, cladophylls, and stem traps. Examples for such plants are Potato, Carrot, Radish, etc. Types of Roots. Chapter 2 - Ecology. For example, some roots are bulbous and store starch. Sometimes roots are modified to perform the basic chemical and physical processes needed by the plant to grow and survive, based on which roots are classified into the following types: 1) Storage roots: They become fleshy to store reserve food materials. Potato is a modified stem and sweet potato is a modified adventitious root. PLAY. Students often commit mistake about the morphology of potato and sweet potato.

Epiphytic roots enable a plant to grow on another plant. This serves to increase the surface area for water and mineral absorption. The roots absorb mineral salts and water from the soil then supply them to other parts of the plants.
