    Study Notes

    Nutrition in Plants

    • Plants can make their own food through the process of photosynthesis, using water, carbon dioxide, and minerals.

    • Animals, including humans, are directly or indirectly dependent on plants for their food.

    • Leaves are the food factories of plants, where photosynthesis occurs with the help of chlorophyll and sunlight.

    • Water and minerals are absorbed by the roots and transported to the leaves through vessels.

    • Carbon dioxide from the air enters the leaves through stomata and is used in photosynthesis.

    • Photosynthesis is a unique process that captures solar energy and stores it in the form of food.

    • Nitrogen, necessary for the synthesis of proteins, is obtained by plants from soil bacteria or fertilizers.

    • Some plants lack chlorophyll and depend on other plants for their food, using the heterotrophic mode of nutrition.

    • Insectivorous plants can trap and digest insects for their nutrients.

    • Fungi use saprotrophic nutrition by absorbing nutrients in solution form from dead and decaying matter.

    • Some fungi can cause diseases in plants, animals, and humans, while others are useful or used in medicines.

    • Symbiotic relationships, such as those between fungi and trees or algae and fungi in lichens, involve the sharing of nutrients and shelter.Nutrition in Plants

    • Fungi are saprotrophs that derive nutrition from dead, decaying matter.

    • Plants like Cuscuta are parasites that take food from the host plant.

    • A few plants and all animals are dependent on others for their nutrition and are called heterotrophs.

    • Most plants are autotrophs, but some adopt other modes of nutrition like parasitic and saprotrophic.

    • All animals are heterotrophs since they depend on plants and other animals for food.

    • Insectivorous plants may be considered partial heterotrophs.

    • Organisms need to take food to obtain nutrients for growth and maintenance.

    • A parasite is an organism that lives on or in another organism and feeds on it, while a saprotroph feeds on dead organic matter.

    • The presence of starch in leaves can be tested through simple chemical tests.

    • Green plants synthesize their own food through the process of photosynthesis, which involves capturing solar energy through chlorophyll pigments.

    • Plants are the ultimate source of food, as they produce organic matter through photosynthesis that sustains all other organisms in the food chain.

    • The pores through which leaves exchange gases are called stomata.
