Modification of Flowering plant- Root and its Modification

                           Morphology of Flowering plant 

Root :-

A -Tap root      B - adventatious Root 

Mainly in exogen plants ,the direct elongation of the bodily structure results in the formation of primary root that grows within the soil .

It bears lateral roots of many orders that square measure remarked as secondary, tertiary, etc. roots.

 the first roots and its branches represent the faucet scheme, as seen within the mustard plant. In monocotyledonous plants, the first root is brief lived and is replaced by an outsized range of roots. 

These roots originate from the bottom of the stem and represent the fibrous scheme, as seen within the wheat plant .

Types of root :-

A –Tap root

B- adventatious root

Root :-

In some plants, like grass, Monstera and therefore the Indian banyan, roots arise from elements of the plant apart from the bodily structure and square measure known as accidental roots .

The main functions of the foundation system square measure absorption of water and minerals from the soil, providing a correct anchorage to the plant elements, storing reserve food material and synthesis of plant growth regulators.

Regions of the foundation :-

Regions of a typical root 

The root is roofed at the apex by a thimble-like structure known as the foundation cap .

 It protects the tender apex of the foundation because it makes its means through the soil. some millimetres higher than the foundation cap is that the region of meristematic activity. 

The cells of this region square measure terribly little, thin-walled and with dense living substance. 

They divide repeatedly. 

The cells proximal to the current region endure fast elongation and enlargement and square measure to blame for the expansion of the foundation long. This region is termed the region of elongation.

The cells of the elongation zone step by step differentiate and mature. Hence, this zone, proximal to region of elongation, is termed the region of maturation.

 From this region a number of the cuticular cells type terribly fine and delicate, thread-like structures known as root hairs. 

These root hairs absorb water and minerals from the soil.

Modification of Root :-

Roots in some plants amendment their form and structure and become changed to perform functions apart from absorption and conductivity of water and minerals. 

they're changed for support storage of food and respiration .

Storage Root 

Tap roots of carrot, turnips and accidental roots of sweet potato, get swollen and store food.

 Hanging a part of  the Indian banyan ,These square measure known as prop roots. 

Similarly, the stems of maize and sugarcane have supporting roots kicking off of the lower nodes of the stem. 

Pneumatophore

These square measure known as stilt roots. In some plants like genus Rhizophora growing in mucky areas, several roots start of the bottom and grow vertically upwards. 

Such roots, known as pneumatophores, facilitate to urge element for respiration
