Plants are also a part of living things that require some form of energy. They have cells and tissues. They also grow in girth and size. And they are the creators of the ecosystem. So, in order to create food, they do have nutrient necessities. Of course, the kind of nutrient requirements differs.
According to the kind of energy source used, autotrophic nutrition in plants can be of two kinds. They are Photo-autotrophic nutrition (where sunlight is the energy is the only source) and Chemo-autotrophic nutrition (where chemicals are the energy is the only source).
Plants that can produce their food are called autotrophs. But, there are some plants that cannot and are known as heterotrophs. The method by which plants produce their own food is known as photosynthesis. The photosynthesis process happens mostly in the leaves of the plant which are also known as the ‘kitchen of the plant’. In certain cases, even the stems have the potential to carry out photosynthesis.
This reaction does not literally happen in the dark but is named so because it is independent of light (no light is needed). This reaction can happen both in the presence and absence of sun rays. Due to the scientists who worked to find out this cycle, this reaction is also known as the Calvin- Benson-Bassham cycle.
For the plants, photosynthesis helps produce glucose to be able to produce energy to perform other functions such as transport of water and minerals throughout the plant and respiration. Plants require energy also to make other biological and biochemical methods to enable it to multiply. For other organisms, plants serve as food.
