What affects the rate of photosynthesis?
Carbon dioxide :- increasing the amount of carbon dioxide levels in the air
around the plant firstly makes the rate of photosynthesis increase
...
At the limiting point the graph levels
off as a constant at this point carbon dioxide is no longer the limiting factor
...
At extremely high light intensities the rate of photosynthesis decreases
as the chlorophyll is damaged
...
Enzymes for the light-independent
system have a higher chance of collisions to form E-S
complexes and these are formed more quickly
...
