    <p>Insectivorous plants are partial heterotrophs since they derive nutrition from other organisms despite being autotrophs. They obtain nutrition by trapping and digesting insects.</p> Signup and view all the answers

    What is the significance of symbiotic relationships in organisms, and how do they benefit the organisms involved?

    <p>Symbiotic relationships are significant for the survival of the organisms involved because they live together and share shelter and nutrients. This association benefits both organisms by providing food, shelter, or protection.</p> Signup and view all the answers

    Study Notes

    Nutrition in Plants

    • Autotrophic nutrition is the mode of nutrition in which organisms make their own food from simple substances, and plants are called autotrophs.

    • Carbohydrates, proteins, fats, vitamins, and minerals are components of food, which are necessary for all living organisms.

    • Leaves are the food factories of plants, and the synthesis of food in plants occurs in leaves through the process of photosynthesis.

    • Chlorophyll, sunlight, carbon dioxide, and water are necessary to carry out the process of photosynthesis, which is a unique process on earth and the ultimate source of energy for all living organisms.

    • Plants cannot absorb nitrogen in its gaseous form, and soil has certain bacteria that convert gaseous nitrogen into a usable form for plants.

    • Saprotrophic nutrition is the mode of nutrition in which organisms take in nutrients in the solution form from dead and decaying matter, and plants that use this mode of nutrition are called saprotrophs.

    • Some plants do not have chlorophyll and depend on the food produced by other plants, and they use the heterotrophic mode of nutrition.

    • Fungi secrete digestive juices on dead and decaying matter and convert it into a solution, and then they absorb the nutrients from it.

    • Rhizobium, a bacterium, takes atmospheric nitrogen and converts it into a soluble form, which it provides to leguminous plants in exchange for food and shelter.

    • Some fungi cause diseases in plants, animals, and humans, but some fungi like yeast and mushrooms are useful and used in medicines.

    • In symbiotic relationships, organisms live together and share shelter and nutrients, and this association is significant for the survival of the organisms.

    • Insectivorous plants are partial heterotrophs since they derive nutrition from other organisms despite being autotrophs.Nutrition in Plants

    • All organisms require food for energy and growth.

    • Green plants are autotrophs that synthesize their own food through photosynthesis.

    • The products of photosynthesis are complex chemical substances like carbohydrates.

    • Chlorophyll and sunlight are essential for photosynthesis to occur.

    • Oxygen is produced as a byproduct of photosynthesis.

    • Fungi are saprotrophs that derive nutrition from dead matter.

    • Some plants, like Cuscuta, are parasites that obtain food from host plants.

    • Heterotrophs are organisms that depend on others for nutrition, including some plants and all animals.

    • Starch can be tested for in leaves using iodine.

    • The ultimate source of food is green plants.

    • The process of photosynthesis involves capturing solar energy and converting it into chemical energy.

    • Plants take in carbon dioxide through their leaves, which is then used in photosynthesis.
