    What are symbiotic relationships in plants and what is their significance in agriculture?

    <p>Symbiotic relationships in plants involve the sharing of nutrients and shelter. For example, the relationship between leguminous plants and nitrogen-fixing bacteria is significant in agriculture because farmers do not need to add nitrogen fertiliser to the soil.</p> Signup and view all the answers

    What are insectivorous plants and how do they obtain their nutrients?

    <p>Insectivorous plants are plants that can trap and digest insects for their nutrients. They may be considered partial heterotrophs as they obtain some nutrients from consuming insects.</p> Signup and view all the answers

    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 and derive nutrition from dead, decaying matter.

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

    • Heterotrophs are organisms that are dependent on others for their nutrition.

    • Symbiotic relationships between plants and microorganisms are of great significance for farmers as they do not need to add nitrogen fertiliser to the soil in which leguminous plants are grown.

    • Most plants are autotrophs, meaning they produce their own food through photosynthesis.

    • Parasitic and saprotrophic plants are exceptions that derive nutrition from other organisms.

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

    • Insectivorous plants may be considered partial heterotrophs as they obtain some nutrients from consuming insects.

    • Chlorophyll is a pigment that enables plants to carry out photosynthesis.

    • Stomata are small openings in the leaves of plants that allow for gas exchange.

    • Nutrient absorption in plants occurs through root hairs.

    • Understanding the different modes of nutrition in plants and animals is essential for understanding ecological relationships.
