Describe modifications of root for specific functions.

$\rightarrow$ Some plants perform some specific functions in addition to their main functions.

$\rightarrow$ For these functions their shape and structure are changed. Such functions are called specific functions and for that the changes that take place in their structure are called modifications.

$\rightarrow$ They are modified for support, storage of food and respiration.

$\rightarrow$ Modifications of plants for food storage :

$(a)$ Food storage in Tap root : Food is stored in tap root of carrot and it becomes cone shaped. Food is stored in Raddish and becomes spindle shaped. Food is stored in beet root and Turnip and becomes top shaped.

$(b)$ Food storage in Adventitious root : Food is stored in adventitious root of sweet potato and get swollen. So it is called simple Tuberous root.

$\rightarrow$ In Asparagus and Dahlia food storing root clusters are formed. They are called Fasciculated tuberous root.

$\rightarrow$ Modifications of root for support: Prop roots and stilt roots are modifications for support.

$(a)$ Stilt Roots : The stems of maize and sugarcane have supporting roots coming out of the lower nodes of the stem. These are called stilt roots. e.g. Maize, Sugarcane, Pandanus etc.
