Question

A photosynthetic unit contains about 230 molecules of chlorophyll, this unit is

• A. Photon
• B. Quantasome
• C. Quantum
• D. All of the above

Answer 1

The correct option is B Quantasome

Quantasomes are particles found in the thylakoid membrane of chloroplasts. in which photosynthesis takes place. The quantasome as seen in a two-dimensional crystalline array is 185 $A^0$ long, 155 $A^0$ wide, and 100 $A^0$ thick. The surface of the quantasome appears to contain four or more subunits. The chlorophyll content is of 230 chlorophyll molecules per quantasome. Photon and quantum are the light energy parameters. Thus option B is correct and other options are incorrect.
