Study Notes
Types of Nutrition
- Two main types: autotrophic nutrition and heterotrophic nutrition.
Autotrophic Nutrition
- Most plants can synthesize their own food via photosynthesis.
- Utilizes carbon dioxide from the air and water from the soil, combined with sunlight and chlorophyll.
- Green plants are categorized as autotrophs, indicating they produce their own food.
Heterotrophic Nutrition
- Animals and non-green plants cannot produce their own food.
- They obtain nutrients from other organisms, relying on plants directly or indirectly.
- These organisms are referred to as heterotrophs.
Photosynthesis Location
- Photosynthesis primarily takes place in green parts of the plant, especially the leaves.
- Leaves are specially adapted for this process, characterized by their thin and flat structure for maximum sunlight exposure.
- Contain numerous chloroplasts, which hold chlorophyll—the pigment that captures solar energy for photosynthesis.
