Mitochondria are present in the pallisade cells and were distributed randomly throughout the cytoplasm directly after dark adaptation. The largest number of chloroplasts are also present in the pallisade cells that makes them the essential site of photosynthesis in the leaves of the plants that contain them, converting the energy in the light to the chemical energy of carbohydrates.
The structures present inside the chloroplast are stacks of thylakoids, called grana, and stroma which is the dense fluid inside of the chloroplasts. It contains the enzyme rubiisco which carry out the light-independent reactions of photosynthesis.
In the matrix of the mitochondria, citric acid or Krebs cycle produce NADH that is used by enzymes planted in the mitochondrial inner membrane to cause ATP where the energy is saved in the form of chemical bonds.
