Their roots are fibrous, leaves have parallel venation; flo:vers are trimerous (each floral parts being 3 in number). The roots in some plants get modified for storage of food, mechanical support and respiration. In contrast, dicots have a taproot system, a tapering root that grows downward and has other roots sprouting laterally from it. The term monocot is short for monocotyledon. In monocotyledonous plants, as well as few dicotyledonous plants, fibrous roots are present. Therefore, rice has fibrous roots just like millet, wheat, sugar cane, and corn among many other monocotyledonous plants. The leaves of the dicot plants have veins that form a branched pattern, unlike monocots, in which they run parallel. The outermost layer is called the epidermis.

Wheat Some examples of dicotyledon include: 1. A fibrous root system, with several moderately branching roots growing from the stem, is common in monocotyledons. The monocotyledonous plants have the adventitious or the fibrous type of root system that do not grow much deeper but spread in the region widely to provide support the plant. Q.1 - Monocot stem has Root Cap. Banana 3. Monocot roots have a larger number of vascular structures than dicot roots. In dicots, the stems have vascular bundles, consisting of two structures, the xylem, and the phloem. Monocotyledonae (Monocots) consists of plants having seeds with one cotyledon and the plants are called monocotyledonous plants. Onion 10. Dicotyledons: The Dicotyledons have tap root system. Maize 9. Monocotyledon Plants are the flowering plants, which has only one cotyledon in the embryo of the plant. Formation of Lateral Roots : In flowering plants, the lateral roots are endogenous in origin, that is, they originate in the inner tissue of the mother root, and appear externally only after their growth is well begun.
