Describe the modifications of roots for specific functions.

(N/A) $\rightarrow$ Roots in some plants change their shape and structure to perform functions other than absorption and conduction of water and minerals. These are called modifications of roots.
$\rightarrow$ Roots are modified for support, storage of food, and respiration.
$\rightarrow$ Modifications for food storage:
$(a)$ Tap root modifications: In carrot, the tap root stores food and becomes cone-shaped (conical). In radish, it becomes spindle-shaped (fusiform). In turnip and beet root, it becomes top-shaped (napiform).
$(b)$ Adventitious root modifications: In sweet potato, adventitious roots become swollen due to food storage, known as simple tuberous roots. In Asparagus and Dahlia, clusters of swollen roots are formed, known as fasciculated tuberous roots.
$\rightarrow$ Modifications for support:
$(a)$ Stilt roots: These are supporting roots that come out of the lower nodes of the stem in plants like maize and sugarcane to provide mechanical support.
$(b)$ Prop roots: These are hanging structures that support the tree, e.g., Banyan tree.
