Nutrition in Plants - Coggle Diagram

- - - - The mode of nutrition in which an organism makes it own food is called autotrophic nutrition.
      - Autotrophs
        
        Organisms that make their own food are called autotrophs
        
        Eg: All green plants
      - Photosynthesis
        
        The process by which plants make their own food using carbon dioxide, water, chlorophyll and sunlight.
        
        Conditions required for photosynthesis
        
        Chlorophyll
        
        It is usually present in the leaves in structures called chloroplasts
        
        Water
        
        The root system of plants enables them to obtain water from the soil. Water and soluble nutrients travel through the root system and the xylem to reach the leaves.
        
        Carbon Dioxide
        
        It is obtained through small openings called stomata mostly present on the underside of the leaves.
        
        When there is enough light and water, the guard cells of the stoma open and allows the carbon dioxide to enter the cells of the leaf
        
        Sunlight
        
        Light energy is absorbed by chlorophyll
    - - The mode of nutrition in which an organism depends on other organisms for food is called.
      - Heterotrophs
        
        Organisms that depend on other organisms for food are called heterotrophs.
        
        Heterotrophic plants
        
        Parasitic Plants
        
        A parasitic plant is one that partially or completely depends on another plant called the host for nutrition.
        
        Eg: Dodder, Mistletoe and Rufflesia
        
        Saprophytic Plants
        
        A saprophytic plant is one that obtains its nutrients from dead and decaying plant and animal matter
        
        Eg: Coral Root, Indian Pipe and Agaricus
        
        Insectivorous Plants
        
        The insectivorous plants are the ones that derive most or some of their nutrition by trapping and consuming animals mainly insects.
        
        Eg: Pitcher plant, Sundew, Bladderworts and Venus flytrap
        
        Symbiotic Plants
        
        Plants that live in association with other organisms, share food and other resources are called symbiotic plants.
        
        Eg: Lichens, Algae and Fungus.
