PHOTOSYNTHESIS
Imiting factors
Lack of
· Water
· Co2
· Sunlight
· High temperature
If plants do not have enough or any of these things then they would not be able to photosynthesise and so produce glucose
LIGHT INTENSITY
More light= faster photosynthesis until gets to max. so with even more light no change in rate of photosynthesis. Sun main energy source; bigger surface area more photosynthesis absorbed.
CARBON DIOXIDE CONCENTRATION
If plant is lacking in CO2 can not make glucose, same as light only effects rate of photosynthesis until gets to max.
TEMPERATURE
Cant be too hot or too cold as higher temperature increases photosynthesis. Higher temperature more energy. But once temperature is at 35C it denatures, stops working, too much rate of photosynthesis drops
Plants use glucose to grow, move, produce protein but for this it also needs nitrate ions (dissovles in water from soil)
