Monocot plants typically have fibrous root systems. Fibrous Roots: Appearance: There is a central primary dominant taproot (also known as the radicle) that grows downward; other hairy roots (known as lateral roots) branch out from it sideways. Fibrous roots have a fine texture and grow just beneath the soil surface branching off in many directions. x�b```f``��������A��b�@̱P�������-{��\�{�� `�,�3=��8��el�Xl. Fold a regular sheet of copy paper in half hamburger (width-wise) style. A mass of many similarly sized roots Adventitious in nature. A taproot system is one in which the primary root becomes the main root of the plant with minimal branching consisting of secondary, smaller lateral roots.The taproot system occurs in dicot plants and is one of the basis of distinguishing these plants from the monocots which generally have fibrous roots. %%EOF Taproot System Fibrous Root System (Monocots) (Eudicots) B. Root Modifications - Many plants have modified roots that perform additional functions for the plant. A taproot is a single, thick root that grows deeper into the soil.
