Warburg studied his effect on

Moll's half leaf experiment was done to show ...................... was required for photosynthesis.

The curve showing the effectiveness of different wavelengths of light in photosynthesis was first given by Engelmann using all,except:

Variegated leaves of a plant were supplied with radioactive carbon dioxide $(^{14}CO_2)$ during an experiment. Leaf $X$ was kept in the dark and leaf $Y$ was kept in the light. At the end of the experiment,the radioactivity in the leaves was measured and found to be as shown in the diagram. What is the most likely explanation for the level of radioactivity found in the yellow zone of leaf $Y$?

Who discovered that green plants take in $CO_2$ and release $O_2$?

What is the byproduct of bacterial photosynthesis?
