Reproduction: Even though roots are not the reproductive part of plants, they are vegetative parts. Thus, through manipulation of ARF19, the level and activity of auxin transporters PIN3 and LAX3 is inhibited. These are described later. Roots perform various functions that are necessary for the survival of the plants. Root systems There are two main types of root systems: tap root and fibrous root system. Absorption: Primary function of the roots is to absorb water and dissolved minerals from the soil. This chakra is located at the navel center.
