Question

what is called adventitious root give an example​

Answer 1

Answer:

Adventitious roots are plant roots that form from any nonroot tissue and are produced both during normal development (crown roots on cereals and nodal roots on strawberry [Fragaria spp.]) and in response to stress conditions, such as flooding, nutrient deprivation, and wounding.

Answer 2

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.
