Solution
The correct option is C K and Mg
Potassium
(K) and Magnesium (Mg) are essential macronutrients for plants.K is absorbed as
K+. In plants, it is required in more abundant quantities in the
meristematic tissues, buds, leaves and root tips. It helps to maintain an
anion-cation balance in cells. It is involved in opening and closing of
stomata.Mg is absorbed by plants in the form of divalent magnesium ion
(Mg2+). It is required in the growing area of roots and stem, seeds,
leaves, etc. It occurs as magnesium pectate in middle lamella. It is responsible
for maintenance of ribosome structure because it is required for the binding of
ribosome subunits during protein synthesis
