Hey Dear,

◆ Macronutrients -

• Nutrients which are required in large amounts for plant growth & function are called macronutreints.
• e.g. oxygen, nitrogen, potassium, magnesium, carbon, calcium, etc.

# Effect of macronutrients -

1. Nitrogen causes cell division & is important constituent of plant proteins.
2. Potassium helps in opening/closing stomata & activation of enzymes.
3. Calcium regulates metabolic activities & cell membrane functioning.

◆ Micronutrients -

• Nutrients which are required in very small amounts for plant growth & function are called macronutreints.
• e.g. iron, boron, silicon, selenium, sodium, zinc, etc.

# Effect of micronutrients -

1. Iron is imp part of enzymes helping in their activation.
2. Copper & zinc are also part of various plant enzymes.
3. Manganese is involved in respiration & photosynthesis by plants.

Hope this helped you. Keep asking..
