In the process of photosynthesis, plants convert sunlight into energy. This occurs primarily in the , which contain a pigment called . During this process, carbon dioxide from the air and water from the soil are used to produce glucose and oxygen. The overall equation for photosynthesis can be summarized as: carbon dioxide + water + sunlight → glucose + oxygen.
Photosynthesis is crucial for life on Earth as it provides the primary source of for nearly all organisms. While plants and some microorganisms are capable of performing photosynthesis, animals rely on these organisms for their . The oxygen produced during photosynthesis is also essential for the survival of most living beings, as it is necessary for cellular respiration.
There are two main stages of photosynthesis: the light-dependent reactions and the light-independent reactions, also known as the . In the light-dependent reactions, sunlight is captured and converted into chemical energy in the form of and NADPH. These reactions take place in the thylakoid membranes of the chloroplasts and require direct light.
In the Calvin cycle, the energy stored in ATP and NADPH is used to convert carbon dioxide into glucose. This cycle does not require light and can occur both during the day and at . The ability of plants to perform photosynthesis ultimately plays a vital role in the , supporting life and influencing the Earth's climate through carbon fixation.
