Detailed explanation-1: -Monocot roots are fibrous, meaning they form a wide network of thin roots that originate from the stem and stay close to the surface of the soil. In contrast, dicots have “taproots, ” meaning they form a single thick root that grows deep into the soil and has smaller, lateral branches.

Detailed explanation-2: -Most monocots are small herbaceous plants, whereas dicots come in all shapes and sizes. One of the reasons for this is that large plants need a good support system, which is provided in dicots by the woody stem and root. Monocots do not often grow into trees, because they do not have any woody tissue.

Detailed explanation-3: -Most monocots are herbaceous annuals or perennials that shoot each season from an underground storage organ (bulb, corm or rhizome) although some do form small woody trees (e.g. Xanthorrhoea).

Detailed explanation-4: -Dicots have a tap root system, while monocots have a fibrous root system. A tap root system has a main root that grows down vertically, and from which many smaller lateral roots arise.
