In flowering plants, roots are mainly of three types: taproot, fibrous root, and adventitious root. 

The taproot system is found in dicot plants, where a primary root grows deep into the soil with lateral branches (e.g., mango, mustard). 

The fibrous root system is found in monocot plants, where a cluster of thin roots arises from the base of the stem, spreading horizontally (e.g., wheat, rice). 

Adventitious roots arise from parts of the plant other than the radicle, such as stems or leaves, and help in support, storage, or propagation (e.g., banyan, sugarcane).
