Study Notes
Overview of Photosynthesis
- Photosynthesis: Process by which plants create their own food using light, primarily occurring in leaves.
- Requires sunlight, water, and carbon dioxide as raw materials.
- Produces glucose (sugar) and oxygen as by-products.
Importance of Water for Plant Growth
- Essential for photosynthesis, transporting nutrients, providing structural support, regulating temperature, and facilitating chemical reactions.
- Maintains turgor pressure, ensuring plants remain firm and upright.
- Evaporative cooling occurs through transpiration, helping stabilize plant temperature.
Mineral Salts and Their Role
- Mineral salts: Essential nutrients needed for plant growth, often supplied via fertilizers.
- Insectivorous plants, which consume insects for nutrients, still require chlorophyll for photosynthesis.
Fertilizers for Plant Nutrition
- Two main types: Organic and Inorganic fertilizers.
Organic Fertilizers
- Derived from natural materials like animal dung, fish, and decomposed plant matter.
- Less expensive and beneficial for soil structure and erosion control.
- Nutrient amount control is more challenging.
Inorganic Fertilizers
- Manufactured chemically and generally more expensive.
- Provide specific nutrient amounts easily and have a longer shelf-life.
- Do not improve soil structure and can contribute to soil erosion.
Differences Between Organic and Inorganic Fertilizers
- Organic: Natural, improves soil health, difficult to store, beneficial for soil erosion control.
- Inorganic: Synthetic, easy to manage nutrient levels, effective for high nitrogen and phosphate demands, but can harm soil structure.
