Answer:
Nutrition is important for a living organisms because it provide components for development maintaining and survive. 2. Green plants synthesize their food with the help of carbon dioxide, water and presence of sunlight and chlorophyll. ... These components of food are necessary for our body and are called nutrients.
The plants use simple chemical substances, like carbon dioxide, water and minerals, for synthesising their food, in the presence of sunlight/light. ... During photosynthesis plants take in carbon dioxide and release oxygen; this released oxygen is utilised by living organisms for their survival.Vessel elements are the building blocks of vessels, which constitute the major part of the water transporting system in those plants in which they occur. Vessels form an efficient system for transporting water (including necessary minerals) from the root to the leaves and other parts of the plant.
Saprophytic refer to an organism which gets its energy from dead and decaying organic matter while symbiotic refer to the organisms that maintain close and long-term biological interaction with other organisms for obtaining nutrients.
