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
