Unlike photosynthesis, cellular respiration occurs in all the eukaryotic cells. Thus, the correct option is D.
Cellular respiration is the process by which the biological fuels such as carbohydrates (glucose sugar) are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy-rich compounds, to drive the bulk production of ATP molecule. This process occurs in all types of eukaryotic cells including plant cells and animal cells.
Photosynthesis is the process of formation of food in the form of carbohydrate (glucose) in the presence of sunlight and carbon dioxide in the chloroplast of plant cell and organisms which contain a chloroplast.
Therefore, the correct option is D.
