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. More »

Photosynthesis is necessary because it forms the basis of the food chain. Photosynthesis, which occurs in green plants and algae, is the process by which sunlight combines with carbon dioxide, water and a chemical called... More »

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, ... More »

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 pro... More »

Photosynthesis is the process that plants use to convert the energy in sunlight into food that they use for energy. In order to carry out photosynthesis, plants need not only sunlight but also water and carbon dioxide. T... More »

Plants produce oxygen as a byproduct of photosynthesis, the process that plants and other organisms use to create usable energy. Photosynthesis consists of carbon dioxide and water reacting in the presence of energy from... More »

Chlorophyll is the pigment used by plants to absorb energy in a process known as photosynthesis. Chlorophyll is a green pigment that is responsible for a plant's colors. When chlorophyll absorbs sunlight as energy, it be... More »
