Expert Answer
Question 37:The green sulfur bacteria uses Hydrogen sulphide instead of water, that is, hydrogen oxygen. So, they can also perform photosynthesis but plant and cyanobacteria releases oxygen which we used for respiration.Option c is the correct answer, green sulphur bacteria releases elemental sulphur.A. It perform anoxygenic photosynthesis, which is without oxygen.B. It uses Hydrogen sulphide instead of water and release elemental sulphur instead of oxygen.C. All rest options are incorrect, because glucose is an organic product not inorganic, oxygen is released when we use hydrogen oxide instead of hydrogen suphide and carbon dioxide is not released by plants.
