Study Notes
Saprotrophic Nutrition
- Saprotrophic nutrition is a mode of nutrition where organisms obtain nutrients from dead and decaying matter.
- Fungi exhibit saprotrophic nutrition, absorbing nutrients from bread, pickles, leather, clothes, and other organic matter.
- Fungal spores are present in the air and germinate on wet and warm surfaces, leading to growth.
Fungi and Their Roles
- Fungi can cause diseases in plants, animals, and humans.
- Some fungi, like yeast and mushrooms, are useful and can be used as medicines.
- Fungi can grow on various substrates, including bread, decayed materials, and rotting wood.
Symbiotic Relationships
- Symbiosis is a relationship where organisms live together and share shelter and nutrients.
- Examples of symbiosis include fungi living inside plant roots and pitcher plants that trap and digest insects.
Pitcher Plant
- Pitcher plants have modified leaves that form a pitcher-like structure, which traps insects.
- The apex of the leaf forms a lid that can open and close the mouth of the pitcher.
- Inside the pitcher, there are digestive enzymes that break down the trapped insects.
Heterotrophs
- Heterotrophs are organisms that depend on others for their nutrition, including animals and some plants.
- Fungi and animals are examples of heterotrophs.
Nutrition in Plants
- Plants are the ultimate source of food and can synthesize their own food through photosynthesis.
- Green plants are autotrophs, meaning they produce their own food using sunlight, water, and carbon dioxide.
- The food synthesized by plants is stored as starch.
