However, roots are also modified to perform various other functions. (2) Plants that are all roots, e.g., Podostemon plant is a thalloid assimilatory root and Monotropa which produces only a free- living root on germination. Buttress roots: they are large roots grown on the side of the tall trees. It is deeper and found in dicot plants. 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. Types of Roots: On the basis of their origin, roots are of two types – tap root and adventitious root. Match. The pitch is absent. Leaves were adapted to optimize photosynthesis. Roots anchor the plant and also absorb water and mineral nutrients. They prevent the tree from falling, and absorb more nutrients and minerals from the ground. This type of reproduction is called vegetative propagation. Sometimes, when perfect growing conditions are provided, the cone roots can reach up to 3 meters in heigt. There are also taproots, fibrous roots and adventitious roots, the third of which are roots sent out from stems and other structures. 3. Fibrous – The fibrous system is another of the types of roots in plants. The former is called straggling rhizome and the latter is known as rootstock rhizome.
