    Study Notes

    Nutrition in Plants

    Modes of Nutrition

    • Autotrophic nutrition: Plants produce their own food through photosynthesis
    • Heterotrophic nutrition: Plants obtain food from external sources (e.g., parasites, insectivorous plants)

    Nutrients Required

    • Macronutrients:
      • Carbon (C)
      • Hydrogen (H)
      • Oxygen (O)
      • Nitrogen (N)
      • Phosphorus (P)
      • Potassium (K)
    • Micronutrients:
      • Iron (Fe)
      • Zinc (Zn)
      • Copper (Cu)
      • Manganese (Mn)
      • Boron (B)
      • Molybdenum (Mo)

    Photosynthesis

    • Process by which plants convert light energy into chemical energy
    • Equation: 6 CO2 + 6 H2O + light energy → C6H12O6 (glucose) + 6 O2
    • Occurs in chloroplasts, organelles found in plant cells

    Nutrient Uptake

    • Roots absorb nutrients and water from soil
    • Xylem transports water and minerals from roots to leaves
    • Phloem transports sugars and other organic compounds produced by photosynthesis

    Soil Nutrients

    • Nitrogen-fixing bacteria convert atmospheric nitrogen into usable forms
    • Mycorrhizal fungi aid in nutrient uptake by forming symbiotic relationships with plant roots

    Nutrient Deficiencies

    • Can cause a range of symptoms, including stunted growth, yellowing leaves, and reduced yields
    • Examples of deficiencies:
      • Nitrogen deficiency: yellowing leaves, stunted growth
      • Iron deficiency: chlorosis (yellowing of leaves), reduced growth

    Nutrition in Plants

    Modes of Nutrition

    • Plants can produce their own food through autotrophic nutrition, specifically via photosynthesis
    • Heterotrophic plants, on the other hand, obtain food from external sources, such as parasites or insectivorous plants

    Essential Nutrients

    • Macronutrients required for plant growth include:
      • Carbon, the basis of organic compounds
      • Hydrogen, essential for water and organic compounds
      • Oxygen, necessary for energy production
      • Nitrogen, crucial for amino acids and proteins
      • Phosphorus, essential for energy production and DNA
      • Potassium, necessary for water balance and energy production
    • Micronutrients, though required in smaller amounts, are still vital for plant growth and include:
      • Iron, essential for energy production and chlorophyll
      • Zinc, necessary for protein synthesis and growth regulation
      • Copper, crucial for enzyme function and plant defense
      • Manganese, necessary for enzyme function and photosynthesis
      • Boron, essential for cell wall formation and sugar metabolism
      • Molybdenum, necessary for nitrogen fixation and protein synthesis

    Photosynthesis

    • The process of photosynthesis converts light energy into chemical energy, producing glucose and oxygen
    • The equation for photosynthesis is: 6 CO2 + 6 H2O + light energy → C6H12O6 (glucose) + 6 O2
    • This process occurs in chloroplasts, organelles found in plant cells, and is essential for plant growth and energy production

    Nutrient Uptake and Transport

    • Roots absorb water and nutrients from the soil
    • The xylem transports water and minerals from the roots to the leaves
    • The phloem transports sugars and other organic compounds produced by photosynthesis throughout the plant

    Soil Nutrients

    • Nitrogen-fixing bacteria, such as Rhizobia, convert atmospheric nitrogen into usable forms for plants
    • Mycorrhizal fungi form symbiotic relationships with plant roots, aiding in nutrient uptake

    Nutrient Deficiencies

    • Nutrient deficiencies can cause a range of symptoms, including stunted growth, yellowing leaves, and reduced yields
    • Examples of deficiencies include:
      • Nitrogen deficiency, characterized by yellowing leaves and stunted growth
      • Iron deficiency, marked by chlorosis (yellowing of leaves) and reduced growth
