ATP or Adenosine Triphosphate is the energy that cells produce in order for an organism to perform well. In plant cells, ATP and glucose are produced during the process of photosynthesis. This process occurs along the cristae or walls of the mitochondria and the chloroplasts.
Chloroplasts are the unique membrane of plant cells where ATP is produced and energy is converted into food that the plants use to sustain themselves. Mitochondria are membranes that are found within most eukaryotic cells (cells with nucleus); they also generate ATP for the plants energy and breakdown glucose (sugar) for the plants food.
