STRUCTURE OF PLANTS

THE ROOT SYSTEM Characteristics of a root Parts of a root Types of a root Modification of root Function of a root

Characteristics of a root The root is the underground, non-green part of the plant. It grows from the radicle of the embryo of seed. It grows into the soil away from sunlight.

Parts of a root When a dicot seed germinate, the radicle gives rise to a long deep-seated root. This is called Primary Root The primary roots get divided into branches which are known as Secondary Roots

Types of a root TAP ROOT SYSTEM. IT consists of a single main primary root with lateral branches arising from it. Long primary root grows vertically downward into the soil. IT is found in dicot plants like castor, pea, mango, gram and beans.

TYPES OF ROOT FIBROUS ROOT SYSTEM IN the fibrous root the primary root is short lived and is replaced after some time by a clusters of thin fibre-like roots. They spread out in the soil give firm support to the plant They are found in monocot plants like wheat, maize, rice, grasses.

Modification of root STORAGE ROOTS SUPPORTING ROOTS NODULATED ROOTS

storage Roots The tap roots of plants such as carrot, turnip and radish are swollen and fleshy as they store food. The plant use this food when required. We also eat some of these roots.

SUPPORTING ROOTS SUPPORTING ROOTS In some plants such as the banyan tree the Indian rubber plant, roots arise from the horizontal branches of the stem and grow towards the soil. On touching the soil they penetrate into it and act as pillars. These pillar like Roots are called prop roots. They support the heavy branches of the tree.

NODULATED ROOTS Peas, beans, groundnuts, moong, urad and gram are a few examples of plants that possess nodulated roots. These plants are called leguminous plants.
