| 3. Which are the most important essential mineral elements for plants? | |
Ans. The most important essential mineral elements for plants are nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S). These elements are required in relatively large quantities and are known as macronutrients.
| 4. What are the functions of essential mineral elements in plants? | |
Ans. Essential mineral elements have various functions in plants. For example, nitrogen is essential for the formation of proteins and chlorophyll, phosphorus is important for energy transfer and DNA synthesis, potassium regulates water balance and enzyme activation, calcium is involved in cell signaling and structural integrity, magnesium is a constituent of chlorophyll, and sulfur is required for amino acid synthesis.
| 5. What are the symptoms of mineral deficiencies in plants? | |
Ans. Mineral deficiencies in plants can lead to various symptoms. For example, nitrogen deficiency may cause stunted growth and yellowing of leaves, phosphorus deficiency can result in poor root development and purplish discoloration of leaves, potassium deficiency may lead to leaf chlorosis and wilting, calcium deficiency can cause blossom end rot in fruits, magnesium deficiency may result in interveinal chlorosis, and sulfur deficiency can lead to yellowing of leaves.
