Why do different plants have a different rate of photosynthesis?

This is saying that they are all green-leafed plants. And how about the different rate of photosynthesis for each plant during the day?

Why do different plants have a different rate of photosynthesis?
well there are differences in size and leaf area, and some species have evolved methods of photosynthesis which are more efficient.
Reply:different plants have different rates of absorption (nutrients and sunlight) which are necessary for photosynthesis to take place. NB: different leaf sizes hence different levels of chlorophyll and therefore different sunlight absorption rates. Also different root systems and hence different rates of nutrient absorption. some plants are taller than others. some also have special abilities for example the slender stems of yams to coil around taller plants in other to reach the sunlight. different plants also have different rates of Transpiration and CO2 absorption and hence the different rates of photosynthesis
Reply:phyllotaxy(arrangement of leaves around the stem)is a major external factor.this differs from plant to plant(variety).this will bring difference in the amount of light absorbed by leaves of same or different plants .the climatic conditions,aquatic or non aquatic conditions also play a major role compared to the internal factors like absorption of nutrients,type of root modification adopted etc.
Reply:I think its due to the surface area of the leafs. The rate of photosynthesis is determined by the size and the location. The bigger the leaf the higher the rate of photosynthesis and vise verse.
