Spirogyra Longata performs photosynthesis to receive its nutrients.  This alga contains special cells called stomata that open and close so the organism can take in carbon dioxide and release oxygen during the chemical reaction in photosynthesis.  It is through the chlorophyll in the chloroplasts that Spirogyra Longata absorbs light.  Chlorophyll reflects all wavelengths of light except for green, which is why it appears green to us.  When the organism absorbed light energy (carbon dioxide), chlorophyll causes the reaction to occur which makes ATP and NADPH.  During this reaction water molecules get split, releasing oxygen into the air. In the case of this organism, a lot of it is released.  Algae use this energy for numerous functions in its cells.  It has also been found that algae also use physics to become efficient.

Spirogyra Longata use this process of photosynthesis to receive its nutrients.  This organism can easily produce lots of oxygen and energy because of its constant submergence in water and  readily available chloroplasts winding throughout its cells.
