All lateral roots arise in acropetal succession i.e. Tap roots and adventitious roots. 4. 5. Prickles (example: rose, Rosa) are modified surface tissues of stem. Roots modified for the storage of food:• Conical roots: modified tap root of conical shape throughout which they store food. These roots remain suspended in air and never touch the ground. Stems elevate the leaves, serve as a conduit from the roots to the leaves, and also generate new growth. Stems connect the roots to the leaves, helping to transport water, minerals, and sugars to different parts of the plant.

The upper surface has a terminal bud and there are many fleshy scaled leaves present. But roots are modified to perform different functions according to habitat. Leaves were adapted to optimize photosynthesis. Rhizomes give rise to adventitious roots from the base. The weak sub-aerial stems are modified into following four types: Aerial roots grow above the ground, typically providing structural support. Aerating roots, which rise above the ground, especially above water, are commonly seen in mangrove forests that grow along salt water coastlines. A plant's primary root is the first root that grows directly from the stem of the plant. A. They include some taproots and tuberous roots. Almost all types of mangroves have these types of roots. The nutrient content of these quasi-root vegetables is unchanged, however. In some orchids and Dahalia, the tubers are branched and are called palmate. They are breathing roots in plants which grow in marshy places and cannot obtain sufficient 02 for respiration. The series of these outgrowths looks like discs stacked one above the other. Aerial roots are found in many different kinds of plants, offering varying functions depending on the location of the plant. (1) Rootless plants, e.g., Wolffia and Epipogium. Buttress roots: they are large roots grown on the side of the tall trees. Carrot (Daucas carota).• Napiform roots: modified tap root, fleshy with the upper portion inflated or swollen and abrupt narrowing of the base into a tail-like portion. 3.

Stems also generally transport nutrients and water from roots to leaves. The buds present on the roots grow as leafy shoots called slips above ground and adventitious roots at their bases. Root vegetables are underground plant parts eaten by humans as food.Although botany distinguishes true roots (such as taproots and tuberous roots) from non-roots (such as bulbs, corms, rhizomes, and tubers, although some contain both hypocotyl and taproot tissue), the term "root vegetable" is applied to all these types in agricultural and culinary usage. 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. This root is further modified into: Prop roots: these grow from the stem of the ground and provide an extra support to the plant. Roots Modified for Vital Functions 1. They give extra support to the plants. D. Bud. 2) CLIMBING ROOTS They are also known as clasping or adhering roots. These roots penetrate into the tissues of the host-plant and establish connection with phloem and thus absorb food and water from it, e.g., Cuscuta. This means that they, like true root vegetables, … Mustard, Carrot, Beetroot, Parsley, China rose and all Dicotyledons are examples of Taproots system. Branch C. Leaf. Sonneratia mangroves develop a flat root system, the underground, horizontally growing roots grow away the trunk and develop cone roots in regular intervals which normally reach a height of 40 to 60cm, measured from the soil to the tip of the cone root. These snake-like roots gradually wrap around the host tree and objects. Epiphytic roots or Hygroscopic roots These adventitious roots are found in some orchids that grow as epiphytes on tree trunks. This root is further modified into: Prop roots: these grow from the stem of the ground and provide an extra support to the plant. Modified Tap Roots 1. dandelions, radishes, and carrots.
