Plants need photosynthesis because the process fuels them with the energy that they require to survive. Plants create energy through photosynthesis by absorbing sunlight and converting it into sugar, lipids, proteins and other organic compounds. These compounds are forms of chemical energy and are fundamental for sustained growth and survival.Continue Reading
The process of photosynthesis, which converts solar energy into chemical energy, takes place in the chloroplasts and through the use of chlorophyll. The resulting chemical energy is stored as sugar in the plants’ leaves. The process of photosynthesis require only light energy, carbon dioxide and water to produce sugar.
Light energy, carbon dioxide and water must be transported to or obtained by the plants’ leaves to undertake photosynthesis. Light energy is typically absorbed by the plant in the form of sunlight. Carbon dioxide is procured through the plants’ stomata, which are tiny pores in the leaves. Water, the third requirement to undertake photosynthesis, is obtained by the plants’ roots and transferred to the leaves through the plants’ tissue system.
Photosynthesis takes place in two distinct stages, known as light reactions and dark reactions. The light reactions occur through the process of absorbing light energy, while the dark reactions are necessary to convert carbon dioxide into sugar.
Plants need photosynthesis to procure energy and create glucose. Moreover, the process provides the majority of the atmosphere’s oxygen, which is of course vital to the survival of all living animals on the Earth.Learn more about Botany
