NEET BIOLOGY

Detailed explanation-1: -Plants also need nutrients for healthy growth. Carbon dioxide is obtained from air. Inorganic ions are obtained from the soil where they are dissolved in water. The three ions required in the greatest amounts are nitrate, phosphate and potassium-sources of nitrogen (N), phosphorus (P) and potassium (K) respectively.

Detailed explanation-2: -Manganese is an essential plant micronutrient . It is absorbed by plants as Mn2+. Manganese is an immobile nutrient and, therefore, deficiency symptoms show up on younger leaves first. A manganese level of 20 to 40 ppm (mg kg–) in plant tissue is sufficient for most plants.

Detailed explanation-3: -Manganese (Mn) is an important micronutrient for plant growth and development and sustains metabolic roles within different plant cell compartments. The metal is an essential cofactor for the oxygen-evolving complex (OEC) of the photosynthetic machinery, catalyzing the water-splitting reaction in photosystem II (PSII).

Detailed explanation-4: -Magnesium fulfills several functions within the plant; it is a central component of chlorophyll which is supporting the function to absorb sunlight during photosynthesis. Magnesium acts as a phosphorus carrier in plants and is essential for phosphate metabolism.
