FAQ (Frequently Asked Questions)

Q1. If a Plant Shows a Symptom Which Could Grow Because of Lack of more than one Nutrient, How Would you Find out by Experiment, the Real Deficient Mineral Element?

Ans. Deficiency symptoms are first concentrated by methods for pot and culture tests. Quickly developing plants which create trademark indications are utilized in culture tests. They are called test (pointer) plants. They are then filled in soil under test in little pots. The outcomes are contrasted with known insufficiency components. Comparative tests are performed with chosen crops.

Q2. How are the Minerals Soaked by the Plants?

Ans. Plants ingest their mineral salt flexibly from the dirt through the roots from the zones of extension and root hair. The minerals are assimilated as particles which are amassed by the plants against their focus in the dirt. The plant shows two stages in mineral retention – beginning and metabolic. In the underlying stage, there is a quick take-up of particles into the external or free space of the cells (apoplast) that involves intercellular spaces and cell dividers. Particles retained in free space are uninhibitedly interchangeable, for example replacing unlabelled K+ particles with marked K+ particles. In the metabolic stage, the particles pass into internal space involving cytoplasm and vacuole. In the inward space, the particles are not openly interchangeable with those of the outside medium. Passage of particles into space is detached retention as no energy is needed for it. Retention of particles into internal space requires energy. It is, consequently, functions to digest the plant food. The development of particles out of the cells formed because of the food intake is called efflux.
