Photosynthesis can be defined as a process of converting light into energy. Plants and some other organisms use this to make their food when required. During this process, plants also convert the carbon dioxide exhaled by us into oxygen. The Sun’s energy is trapped by chlorophyll, a green pigment present in plants’ leaves. This entire process is affected by temperature, intensity and wavelength of light and carbon dioxide level. Photosynthesis is responsible for balancing the atmospheric oxygen and carbon dioxide levels.
Fast Facts: –
- Photosynthesis consists of two series of biochemical reactions, the light reactions and dark reactions.
- This process provides us with most of the oxygen that we breathe.
- Photosynthesis is one the many examples of how people and plants are dependent on each other in sustaining life.
- This process is the reason why conifers and other pine trees grow in a cone shape.
- The veins of a plant that pulls water from the soil are called xylem.
- Chlorophyll uses the absorbed energy to split water molecules into oxygen and hydrogen.
- Algae are capable of photosynthetic generation of energy.
- The supply of earth’s organic compounds and energy required to sustain the life are dependent on photosynthesis.
- Plants are not the only organisms that use photosynthesis to make food. A sea slug also has been discovered that makes food by using the process.
- During the process, glucose gets stored in plants that can be found in roots and fruits of the plant.
