Why do plants form adventitious roots?
Adventitious roots facilitate gas transport and water and nutrient uptake during flooding. Following flooding, they help take up nutrients and ensure plant survival (Sauter, 2013).
What vegetables have adventitious roots?
Solanaceous vegetables (tomatoes, peppers, eggplant) can generate new roots from both the existing transplant root system and also from stem tissue. Stem generated roots are called adventitious roots and in solanaceous transplants they can grow at any place along the stem above the root system.

Why do monocots have adventitious roots?
In monocot plants, the radical root is short lived and later replaced by a number of adventitious roots, which form organs of other roots like the stem. Because the adventitious roots are extensive and cling to soil particles, monocot plants are useful in preventing erosion.
What ecological advantage might a plant gain by the ability to produce adventitious roots?
Aquatic adventitious roots (aquatic roots) are commonly formed in flooding-tolerant plant species and are generally assumed to be beneficial for plant growth by supporting water and nutrient uptake during partial flooding.
