Study Notes
Plant Roots and Nutrition
- Roots are responsible for water and nutrient absorption in plants.
Essential Elements for Plant Growth
- An element is considered essential for plant growth if it meets three criteria: • It is necessary for normal plant growth and reproduction. • A plant cannot complete its life cycle without it. • No other element can replace its function.
Factors Influencing Root Growth
- Multiple factors can influence root growth, including: • Nutrient availability • Water availability • Temperature • Light • Oxygen availability • Microorganisms • Genetic factors
Role of Plant Roots
- Plant roots respond to variations in nutrient availability by adapting their growth and morphology.
- The main function of plant roots is to absorb water and minerals from the soil.
- Plant roots also anchor the plant in the soil and store food.
Inhibitors of Root Growth
- Factors that can inhibit root growth include: • Waterlogging • Drought • Salinity • Extreme temperatures • Toxic chemicals • Limited nutrient availability
