how do plants get the sunstances it needs for photosynthesis

Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water; the energy source is sunlight; and the end-products are oxygen and (energy rich) carbohydrates, for example sucrose, glucose and starch.
Carbon dioxide is collected through tiny pores in their leaves called stomata from the atmosphere, and water through the root system and the stem from the soil.

Lets work the way bacak, and also be more precise.

The end product of photosynthesis is glucose which is formed by the Carbondioxide present in the air , the water that comes from the ground.the energy is need to drive the reaction that comes from the wavelength the sunlight has got. Usaully red and blue are found to be most effective in photosynthesis. That's why the light when fall on the green paprts of the plant, triggers the electrons in the waters and change it to free oxygen ,the electron to drive the reaction comes from this elcetron of the oxygen. That goes on forming glucose and gives out carbondioxide by passing through different steps.



You can get it easily on wikipedia.

Agreed. The plants make glucose which is the portable chemical energy source the plants use to synthesize the other molecules it needs.

For the most part, the plant absorbs the minerals and water from the ground. It absorbs carbon dioxide from the air. Chlorophyll absorbs the sunlight and converts it to chemical energy. There are also typically bacteria on the plants roots that also help to metabolize minerals in the ground into a form that used by the plants.
