A taproot develop from the radicle of the embryo and becomes the main root. It branches further into secondary and tertiary roots. The tap root grows deep beneath the soil and is always present underground. Tap roots are found in dicot plants. Firbrous roots grow from parts of the plant other than the radicle, like the stem or leaves. They do not have a single primary root because the embryonic root dies when the plant is still young. They are slender, fibrous and they do not grow deep into the soil but branch out in the superficial layers of the soil. Fibrous roots can be found as underground roots or aerial roots. These roots are found in monocot plants.
