Roots

The study of assorted external options of the plants is understood as plant morphology. 

The angiosperms  is characterized by presence of roots, stems, leaves, flowers, and fruits. 

These are the most important characteristics of angiosperms. 

Root

The root is underground a part of the plant and developed from elongation of raddicle. 

There are four main functions of the foundation system 

1. The absorption of water and minerals from the soil. 

2. Providing a correct anchorage to the plant elements. 

3. Storage of reserve food material. 

4. Synthesis of plant growth regulators.

 There area unit in the main three kinds of roots. 

1. Tap root- It originates from radicle. 

Example- herbaceous plant, turnip, and carrots. 

2. Fibrous root- It originates from the bottom of the state. 

Example- wheat and paddy. 

3. Adventitious root- It originates from the part of a plants aside from bodily structure. 

Example- Ficus bengalensis (proper roots), maize (stilt roots). 

The apex of the foundation is roofed by a thimble- like structure referred to as plant organ, it protects the tender apex of the foundation whereas, creating approach through soil. 

Above the foundation cap region of meristematic activity, having little cells with dense protoplasm. 

The half on top of the region of meristematic activity is the region of elongation wherever cells bear elongation and enlargement to extend the length of the foundation. 

Region of maturation contains root hairs that facilitate within the absorption of water and minerals. 

Modification of roots 

 Roots are changed for storage, organic process, aeration and support.

 The taproot of carrot, turnip and adventitious roots of sweet potato gets swollen to store food. 

Proper root of a banyan and stilt root of maize and sugarcane have supporting roots coming out from the lower node of the stems. 

In Rhizosphere, pneumatophores area unit gift that facilitate to induce atomic number 8 for respiration as it grows in slough areas.
