Photosynthesis begins when a plant's chlorophyll in the chloroplasts capture energy from the sun. Water is taken up from the soil, and carbon dioxide enters the leaves through the stomates. The light energy is used to co... More »

The two stages of photosynthesis are light reactions and the Calvin cycle; light reactions take place first, forming the photo portion of photosynthesis, while the Calvin cycle follows, completing the cycle with several ... More »

Water is important for photosynthesis because it the source of hydrogen for the sugars created through photosynthesis. The simple sugars created through photosynthesis have six carbon atoms, 12 hydrogen atoms and six oxy... More »

Plant leaves contain chloroplasts, which have chlorophyll that absorbs light energy from the sun. Chlorophyll is the green pigment that is important for the process of photosynthesis in plants. More »

In plant cells, chloroplasts perform photosynthesis, a process that converts light energy from the sun into chemical energy in the form of glucose. Plants can later use this stored chemical energy to carry out activities... More »

Sunlight is needed for photosynthesis because the solar energy is what is converted to chemical energy by the plant's chloroplasts. This energy is necessary for the production of glucose, which provides usable energy for... 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 »
