SSC MTS EXAM

Detailed explanation-1: -Its functions in plant growth and development include osmotic and stomatal regulation, evolution of oxygen in photosynthesis, and disease resistance and tolerance. At adequate levels of supply, Cl improves the yields and quality of many crops such as onions and cotton if the soils are deficient in this nutrient.

Detailed explanation-2: -Cl− (chloride) is rightly regarded as an essential micronutrient for oxygenic photosynthetic organisms, first noted by Arnon and Whatley (1949) (see below), and is generally present in the environment at concentrations well in excess of what is needed to satisfy the micronutrient requirement.
