modified adventitious root.
Asparagus is the example of a modified adventitious root in which roots are modified for the storage of food. The adventitious roots are generally developed from the stem nodes, intermodal, leaves, etc. These roots are modified for various purposes such as food storage, respiration, and support of plants.

What are the modification of roots?
These modified roots usually are swollen and assume different forms such as spindle shaped, e.g., radish; top shaped, e.g., beet, turnip; conelike, e.g., carrot; indefinite shape, e.g., sweet potatoes (Fig. 7.1). Dahlia, Asparagus, Portulaca are some other examples of plants with modified roots for food storage.
Which of the following is an example of modified root?

What type of modification of root is found in turnip?
tap root
The type of modification found in Turnip ( Brassica rape) is tap root, and they contribute to food storage. The roots of carrots, radishes, and sweet potatoes have similar kinds of root-like Turnips which aim to store food.
What are the examples of adventitious roots?
Adventitious roots include those formed on stem and leaf cuttings and those produced by air layering. Adventitious aerial roots of many tropical trees are common. For example, Ficus produces free-hanging aerial roots that originate in the branches and undergo secondary thickening before they reach the soil.
What type of modification of root is found in mangrove trees?
Pneumatophores
(c) Root Modification in Mangrove Trees: Pneumatophores (negatively geotropical root branches of tap root system).
What is a modified stem of a plant?
A rhizome is a modified stem that grows horizontally underground; it has nodes and internodes. Vertical shoots may arise from the buds on the rhizome of some plants, such as ginger and ferns. Corms are similar to rhizomes, except they are more rounded and fleshy (such as in gladiolus).

stem structure
In asparagus (Asparagus officinalis; Asparagaceae), the scales found on the asparagus spears are the true leaves. If the thick, fleshy asparagus spears continue to grow, flat, green, leaflike structures called cladodes develop in the axils of the scale leaves.
