The number of chlorophyll molecules in a quantasome is

The correct option is D 200-250
The photosynthetic unit having 200-250 chlorophyll molecules is called quantasome. It is present in the thylakoid membrane of chloroplast of plant cells. It was discovered by Park and Biggins. They are formed equally of lipids and proteins. Its dimensions are 185 A long, 155 A wide and 100 A thick. In quantasome, pigments are found to be present on the basis of absorption spectra in the form of the pyramid. Enzymes required for the process of photophosphorylation are located in quantasome of the chloroplast.
