Detailed explanation-1: -There are actually 20 mineral elements necessary or beneficial for plant growth. Carbon (C), hydrogen (H), and oxygen (O) are supplied by air and water. The six macronutrients, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S) are required by plants in large amounts.
Detailed explanation-2: -The 17 Essential Plant Elements include nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, chlorine, iron, manganese, zinc, copper, molybdenum, and nickel. The non-mineral essential plant elements include hydrogen, oxygen, and carbon. These are either taken up as a gas or water.
Detailed explanation-3: -Plants absorb water from the soil and take it in through their roots. The water travels up the stem and reaches the cells in the leave. Plants must have water to allow the nutrients to be absorbed. Plants allow carbon dioxide from the air to enter their leaves through tiny holes, and it enters the leaf cells.
