Photosynthesis is the ultimate source of the energy for all the food that humans require, as well as the source of the energy used to build the biological materials that humans use, such as wood, cotton and wool. It is also the major source of oxygen gas that all animals require.Know More
Photosynthesis is the conversion of carbon dioxide and water into carbohydrates using energy from sunlight. It is the main process by which new energy becomes available to life on Earth. Plants and algae use photosynthesis to convert light energy into a form available to other organisms, and thus form the base of almost every food chain. Animal materials and foods can also be traced back to this source of energy and materials.
Beyond the immediate energy and materials that photosynthesis provides, it is also the source of the energy stored in fossil fuels, which come from the decomposition of buried organisms without oxygen. These decayed remains are subjected to geological processes, such as heat and pressure, for millions of years to become coal, oil and natural gas. These together make up over 85 percent of humans' energy use. Photosynthesis is also an important factor in reducing the damage many scientists worry about due to carbon dioxide levels.Learn more in Botany
Photosynthesis is the process by which green plants manufacture their own food. The process takes place in small structures within the plant’s cells called chloroplasts. Photosynthesis evolved about 3 billion years ago, yet it remains the most important method for harvesting the sun’s energy on the planet.Full Answer >
Photosynthesis is the process by which plants turn light energy into chemical energy. Plants also need carbon dioxide and water along with the light to complete the process.Full Answer >
Photosynthesis, the process by which plants convert the sun's energy to glucose, takes place during daylight hours when the plant's leaves are exposed to sunlight. This process only occurs in green plants and in some protist species. Carbon dioxide and water must also be present in order for photosynthesis to occur.Full Answer >
Photosynthesis is a complex process divided into two stages by plant biologists. The first stage is the light-depended reaction, while the second stage is the light-independent reaction or dark reaction.Full Answer >
