Question

concentration of what always increases rate of photosynthesis? ​

Answer 1

An increase in the concentration of carbon dioxide gives an increase in the rate of photosynthesis. It is difficult to do this out in the open air but is possible in a greenhouse. Figure 3. The rate of photosynthesis increases linearly with increasing carbon dioxide concentration (from point A to point B on the graph).
