In a way green plants and cyanobacteria have synthesised all the food on the earth. Comment . |

Answer» Cyanobacteria are unicelluar prokaryotic organisms. Besides, some primitive cellular cell organelles, they have photosynthetic lamellae where photosyntheic pigments are present. There are chlorophyll-ac, phycocyanin and phycoerythrin. These coloured pigments impart typical blue green colour to the bacteria and enable them to manufacture food for themselves and aquatic animals. Green plants are multicellular organisms capable of making food by using `CO_(2),H_(2)O` and light energy in special cell organelles called chloroplast. So, bacteria and green plants make food for living organisms on earth. |
