    Study Notes

    Modes of Nutrition in Plants

    • Autotrophic Nutrition: Plants prepare their own food through photosynthesis, using light energy, water, and carbon dioxide to produce glucose and oxygen.

    Essential Nutrients for Plant Growth

    • Macronutrients:
      • Nitrogen (N): necessary for amino acid synthesis and protein production
      • Phosphorus (P): involved in energy transfer, DNA synthesis, and root development
      • Potassium (K): regulates water balance, stomatal opening, and enzyme activation
    • Micronutrients:
      • Iron (Fe): essential for photosynthesis, respiration, and enzyme function
      • Zinc (Zn): involved in enzyme regulation, protein synthesis, and wound healing
      • Boron (B): necessary for cell wall formation, sugar metabolism, and flower development

    Mechanisms of Nutrient Uptake

    • Root Hairs: increase surface area for absorption of water and minerals
    • Ion Channels and Pumps: regulate ion transport across cell membranes
    • Mycorrhizal Association: symbiotic relationship between plant roots and fungi enhances nutrient uptake

    Soil Factors Affecting Plant Nutrition

    • pH: affects nutrient availability and root growth
    • Water Availability: influences nutrient uptake and transport
    • Soil Texture and Structure: impact root growth, aeration, and water infiltration
