Root System

Roots are brown, non-green, underground parts of plants. They are collectively referred to as root systems. There are three types of root systems:

Taproot System

Taproots are mainly found on dicotyledonous plants. The taproot system develops from the seed radicle, along with its primary roots and branches. Dicotyledonous plants with taproot systems include mustard seeds, mangoes, grains, and banyans.

The Fibrous root System

Fibrous roots are primarily found in ferns and monocotyledonous plants. The roots of this plant grow from the stem in thin, moderately branching roots or primary roots. Because fibrous roots do not penetrate deep into the soil, they look like a carpet or mat when fully matured. Monocotyledonous plants with fibrous roots include wheat, paddy, grass, carrots, onions, grass, and grass.

The Adventitious root System

The adventitious root system is composed of roots that originate from parts of the plant body other than the radicle. All monocotyledonous plants have this type of root system. The adventitious root system is used by plants for many purposes, including mechanical support, vegetative propagation, etc. Banana trees, maize, oak trees, and horsetails are monocotyledonous plants with adventitious roots.
