<span>The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf. Water enters the root and is transported up to the leaves through specialized plant cells known as xylem vessels.</span>

ATP is the energy currency of living organisms. Not to get too technical, but it's a molecule with three phosphate groups (ATP stands for adenosine tri-phosphate). When energy is needed, one of those phosphate groups is broken off (making ADP - adenosine di-phosphate) and the energy stored in that bond is released.
To get ATP, cells use mitochondria (the powerhouse of the cell ;) ) to convert sugars into ATP through cellular respiration. Starch is one of these sugars. Therefore, starch is used to <em>store </em>energy long-term, and when energy is needed it's converted to ATP. Then, processes that require energy use that ATP.
Hope that helps! Feel free to message me or leave a comment if you need clarification or anything :)
