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.
