light provides what for photosynthesis?

As the light level is raised, the rate of photosynthesis...
increases steadily but only upto a certain point. After that it wont make a differnce becuase then itll be either the temp of carbon dioxide level which is the limiting factor
3 of 15
The amount of carbon dioxide will only increase...
the rate of photosynthesis up to a point.
4 of 15
If the temperature is limiting its becuase its..
too low
5 of 15
If the temp is too low...
the enzymes needed for photosynthesis work more slowly at low temperatures
6 of 15
If the plant gets too hot..
the enzymes it needs for photosynthesis and its other reactions will be damaged. This happens at about 45 degrees.

You can artificially create the ideal conditions for farming in a...
greenhouse
8 of 15
Greenhouses help to trap the..
suns heat and make sure that the temperature doessnt become limiting.

In winter a gardener/farmer may use a..
heater aswell to kepp the temperature at the ideal level.
10 of 15
In summer it may get too hot so farmers/gardeners...
can use shaded and ventilation to cool things down.
11 of 15
Light is always needed for photosyntheseis so farmers/gardners may use...
artificial light especially at night to give their plants more quality photosynthesis time.
12 of 15
Farmers can use a parrafin heater to increase the amount of...
Carbon dioxide in the greenhouse. As the paraffin burns it makes Carbon dioxide as a by-product.
13 of 15
Keeping plants enclosed in agreenhouse helps...
protect them from insects and diseases. The farmer can add fertilisers to the soil to provide the minerals needed for healthy growth
14 of 15
Doing all this costs the farmer/gardner a lot of mney. But..
if the farmer can keep the conditions right for photosynthesis, the plants will grow faster and a decent crop can be harvested much more often, which then can be sold.
