NEET BIOLOGY

Detailed explanation-1: -Sulphur. Sulphur is a component in the formation of chlorophyll. Deficiencies result in yellow leaves and stunted growth.

Detailed explanation-2: -Phosphorus deficiency tends to inhibit or prevent shoot growth. Leaves turn dark, dull, blue-green, and may become pale in severe deficiency. Reddish, reddish-violet, or violet color develops from increased anthocyanin synthesis. Symptoms appear first on older parts of the plant.

Detailed explanation-3: -Yellowing leaves on plants may often be a sign of too little or too much water or nutrients which can affect plant performance. Your plant may also be located in too much light where it is scorching, or too little light where it is fading due to an inability to photosynthesize properly.

Detailed explanation-4: -Nitrate deficiency Without nitrates, the amount of chlorophyll in leaves reduces. This means leaves turn a pale green or yellow colour. This reduces the plant’s ability to photosynthesise and grow properly, which reduces the farmers’ crop yield .
