3- Inhibition of cell division

5- Stunted plant growth
Chlorosis or loss of chlorophyll leads to the yellowing of leaves. It is caused by the deficiencies of nitrogen, potassium, magnesium, sulphur, iron, manganese, zinc, and molybdenum.
Necrosis is the death of plant tissues as a result of the deficiencies of calcium, magnesium, copper, and potassium.
Inhibition of cell division is caused by the deficiencies of nitrogen, potassium, sulphur, and molybdenum.
Delayed flowering is caused by the deficiencies of nitrogen, sulphur, and molybdenum.
Stunted plant growth is a result of the deficiencies of copper and sulphur.

1- Macronutrients: They are the nutrients required by plants in large amounts. They are present in plant tissues in amounts more than 10 m mole kg–1 of dry matter. Examples include hydrogen, oxygen, and nitrogen. 2- Micronutrients: They are also called trace elements and are present in plant bodiesRead more
1- Macronutrients: They are the nutrients required by plants in large amounts. They are present in plant tissues in amounts more than 10 m mole kg–1 of dry matter. Examples include hydrogen, oxygen, and nitrogen.
2- Micronutrients: They are also called trace elements and are present in plant bodies in very small amounts, i.e., amounts less than 10 m mole kg– 1 of dry matter. Examples include cobalt, manganese, zinc, etc.
3- Beneficial nutrients: They are plant nutrients that may not be essential, but are beneficial to plants. Sodium, silicon, cobalt and selenium are beneficial to higher plants.
4- Toxic elements: Micronutrients are required by plants in small quantities. An excess of these nutrients may induce toxicity in plants. For example, when manganese is present in large amounts, it induces deficiencies of iron, magnesium, and calcium by interfering with their metabolism.
5- Essential elements: These elements are absolutely necessary for plant growth and reproduction. The requirement of these elements is specific and
non-replaceable.
They are further classified as macro and micro-nutrients.
Hydroponics is the art of growing plants in a nutrient solution in the absence of soil. Since the plant roots are exposed to a limited amount of the solution, there are chances that the concentrations of oxygen and other minerals in the plant roots would reduce. Therefore, in studies involving minerRead more
Hydroponics is the art of growing plants in a nutrient solution in the absence of soil. Since the plant roots are exposed to a limited amount of the solution, there are chances that the concentrations of oxygen and other minerals in the plant roots would reduce. Therefore, in studies involving mineral nutrition using hydroponics, purification of water and nutrient salts is essential so as to maintain an optimum growth of the plants.
Plants tend to absorb different kinds of nutrients from soil. However, a nutrient is inessential for a plant if it is not involved in the plant’s physiology and metabolism. For example, plants growing near radioactive sites tend to accumulate radioactive metals. Similarly, gold and selenium get accuRead more
Plants tend to absorb different kinds of nutrients from soil. However, a nutrient is inessential for a plant if it is not involved in the plant’s physiology and metabolism. For example, plants growing near radioactive sites tend to accumulate radioactive metals. Similarly, gold and selenium get accumulated in plants growing near mining sites. However, this does not mean that radioactive metals, gold, or selenium are essential nutrients for the survival of these plants.
