Study Notes
Modes of Nutrition
- Organisms that derive nutrition from dead and decaying matter are saprotrophs.
- A few plants and all animals are considered heterotrophs because they cannot synthesise their own food.
Carnivorous Plants
- A plant that traps and feeds on insects is known as an insectivorous plant.
- Green plants that synthesise their own food are autotrophs.
- The main feature of plants that can trap insects and digest them is the presence of digestive enzymes.
- Insectivorous plants do not resemble green plants because they have adapted to obtain nutrients from insects due to a lack of essential nutrients in their environment.
Photosynthesis
- In photosynthesis, plants take in carbon dioxide and release oxygen respectively.
Fungi
- Fungi are organisms that lack chlorophyll and cannot make food by photosynthesis.
- Fungi acquire nutrients by breaking down dead and decaying organic matter.
- The mode of nutrition in which organisms take in nutrients from dead and decaying matter is called saprotrophic nutrition.
- Fungi growing on pickles, leather, and clothes due to hot and humid weather represent saprotrophic mode of nutrition.
- The fluffy umbrella-like patches that grow on rotting wood during the rainy season are white in color.
Fungi-Plant Relationships
- The relationship where some fungi live inside the roots of plants and share shelter and nutrients is known as mycorrhizal relationship.
Fungi and Disease
- Fungi can cause diseases in other organisms.
- Fungi that cause harm to other organisms are categorized as pathogens.
- In the context of Boojho's grandfather's wheat fields being spoiled, a fungus is an example of a pathogen.

Description
Test your knowledge on organism nutrition, photosynthesis, and different types of organisms like saprotrophs and heterotrophs. Questions cover topics such as why organisms take food, differences between parasites and saprotrophs, testing the presence of starch in leaves, and the process of synthesis.
