Internal factors that affect the rate of photosynthesis:

1. Leaf anatomy.
2. Plant hormones.
3. The amount of chlorophyll.
4. Enzyme activity of the Calvin cycle.
5. The capacity of metabolite transport processes.

External factors that affect the rate of photosynthesis:

1. Temperature
2. Soil pH levels
3. Light intensity
4. Climatic conditions
5. Carbon dioxide concentration
