Which organelle is NOT involved in the photosynthesis process?

Ribosomes are responsible for protein synthesis in the cell and do not play a direct role in the photosynthesis process. Photosynthesis primarily occurs in chloroplasts, which contain chlorophyll needed to capture light energy. Plastids, which include chloroplasts, are known for their involvement in the storage and synthesis of various substances, including pigments necessary for photosynthesis. Mitochondria, while primarily involved in cellular respiration, are not directly engaged in photosynthesis but do function in the overall energy metabolism of the cell, highlighting their importance in cellular energy production. Ribosomes, on the other hand, do not have a function in photosynthesis or the processes directly associated with it, such as the capturing of light energy or the conversion of carbon dioxide and water into glucose.
