Haustorial root is present in (1) Zea mays (2) Cactus (3) Cuscuta (4) Monotropa

Answer: (3)

The root is an underground part of the plant that absorbs water and minerals from the soil and anchors the plant firmly.

In some plants, the roots change their shape and get modified to absorb and transport water and minerals from the soil to different parts of the plant. They are also modified for support, food storage, and respiration

Sucking or Haustorial roots – These roots are found in parasitic plants. Parasites develop adventitious roots from the stem which penetrate into the tissue of the host plant and suck nutrients.

Examples: Cuscuta (dodder), Cassytha, Orobanche (broomrape), Viscum (mistletoe), Dendrophthoe.
