Which wavelength of light carries out photosynthesis in bacteria?

The energy of a mole of light quanta is $72 \ kcal$ in the blue region at $400 \ nm$ and $41 \ kcal$ in the red region at $700 \ nm$. How much light energy would be required under standard conditions to make $1 \ mole$ of glucose costing $686 \ kcal$?

During daylight hours,the rate of photosynthesis is higher than that of respiration,and the ratio of oxygen produced to that of consumed is (in $:1$)

Photophosphorylation differs from oxidative phosphorylation in:

Oxygenic photosynthesis occurs in

Algae and other submerged plants float on the water surface during the day and sink to the bottom at night because...
