Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods. In mature agoho or horsetail tree (Casuarina equisetifolia) and certain plants, clonal seedlings or offshoots are commonly seen growing profusely around the trunk from horizontally growing roots. The root serves as storage organ for water and carbohydrates as in the modified, swollen roots of carrot, sweet potato (camote) and yam bean (sinkamas). Main Function The main function of the root system of a plant is to absorb water and minerals from the soil while providing support to the plant on the ground. 5. The root differs from the stem mainly by lacking leaf scars and buds, having a root cap, and having branches that originate from internal tissue rather than from buds. All the roots and root hairs convert to an equivalent total absorptive surface area in contact with the soil of almost 640 sq meters (Went and The Editors of Life 1963; Feininger 1968; Mader 1993). The plant root system absorbs water and nutrients from the soil in mineral solution, mainly through the root hairs. Chloroplasts are absent in roots. Hence, roots are very important. Plants that grow in stagnant water or other watery places have modified roots called pneumatophores to which oxygen from the air diffuses. Plants with a fibrous root system are more efficient in absorption from shallow sources. The taproot of a plant grows straight down and is very thick. The tap root and its branches constitute the tap root system. The first root in seed producing plants is the radicle, which expands from the plant embryo after seed germination. Redwood trees (a gymnosperm) about 100 meters tall have stood erect for thousand years only because millions of individual fibrous roots dig into the ground, even though the depth of penetration is only up to about 5 meters. These branch to produce what are called tertiary roots. 2. There are three levels of integrated organization in the vegetative plant body: organ, tissue system, and tissue. Angiosperm - Angiosperm - Structure and function: The wide diversity in the morphological features of the plant body has been discussed above. A common way to differentiate root types is by whether the root system is fibrous or a taproot system. In mathematics, a root system is a configuration of vectors in a Euclidean space satisfying certain geometrical properties. Reproduction. Tap root system. As reviewed by Gomez and Prado (2007), coconut roots usually grow to a depth of close to 0.80 m with 60-90% found in the top 0.5 m of the soil. Adventitious root system. (adventitious roots),  all with root hairs close to the tip and terminal root caps. Observation: It would not be easy to pull out the grass and something would prevent the grass from being pulled out. When the plant embryo emerges from the seed, the radicle of the embryo forms the root system. It elongates to form primary or the tap root. Growth and function of the sugarcane root system D.M. Quantitative investigation revealed that a single rye plant (, volume of about 2 cu ft (0.057 cu. Adventitious roots are still roots, and therefore, their main function is the absorption of minerals and water. Absorption of Minerals: Roots absorb mineral salts […] All the roots and root hairs convert to an equivalent total absorptive surface area in contact with the soil of almost 640 sq meters (Went and The Editors of Life 1963; Feininger 1968; Mader 1993). 6. In the desert plants called phreatophytes like the mesquite, the roots seek permanent underground water reserves. The secondary functions are specialized one and are performed only by those roots which are modified accordingly. Put a carrot in a glass of water containing some blue colouring agent. Carefully dig out some grass and see what prevented the grass from being pulled out. meter) had a total root length of 387 miles (623 km) or an average root growth of about 3 miles (4.83 km) per day. Photosynthesis. Redwood trees (a gymnosperm) about 100 meters tall have stood erect for thousand years only because millions of individual fibrous roots dig into the ground, even though the depth of penetration is only up to about 5 meters. The root tip can be divided into three zones: a zone of cell division, a zone of elongation, and a zone of maturation and differentiation (Figure 2). In monocot plants, the tap root is short lived and soon replaced by adventitious roots. Functions of Roots: Roots perform two kinds of functions — Primary and Secondary.
