Biology · Secondary 4 · Hard · Factors affecting photosynthesis
A graph shows the rate of photosynthesis against carbon dioxide concentration for two identical plants, X and Y. Curve X levels off at a lower rate and at a lower carbon dioxide concentration than curve Y. Temperature is the same. What best explains the difference between X and Y?
- Plant X receives a lower light intensity than plant Y.
- Plant X has more chlorophyll than plant Y.
- Plant X has a higher carbon dioxide concentration than plant Y.
- Enzymes in plant Y are denatured at all carbon dioxide concentrations.
