Root:-

✒The part of a plant that grows downward and holds the plant in place, absorbs water and minerals from the soil, and often stores food.

Adventitious roots:-

✒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.
