Task: Named Entity Recognition
Input (English): Carbon dioxide enters the leaf through the stomates. Water is absorbed by the plant and transported to the leaves. Sunlight is captured by the plant. Energy in the form of ATP is made from the sun's energy. Carbon dioxide, water, and ATP form sugars via the Calvin cycle. Oxygen is given off as a byproduct. Oxygen leaves the leaf through the stomates. Water is reused or it leaves the leaf. The sugars can be used by the plant to make cellulose. 
Output (English): atp ,carbon dioxide ,water ,cellulose ,oxygen ,sugars ,sunlight; sun's energy
