what are the limiting factors in photosynthesis?
light intensity
CO2 concentration
temperature
what is the compensation point ?
the point at which the organic compounds made by photosynthesis will exactly match the amount of organic compounds being used in respiration
why does more light increase the rate of photosynthesis?
more light means electrons are more excited on chlorophyll and are emitted so more electrons pass down the elcetron transport chain so more ATP is produced and more NADPH is formed
why are glasshouses used ?
heating them prevents night temperatures falling to low & allows the growers to provide optimum temp for growth
