List two factors that affect the rate of photosynthesis

Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature.1. Light intensity. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide.
2. Carbon dioxide concentration.
3. Temperature.

Only algae, oak trees, and bermuda grass produce atp by photosynthesis i am almost positive
