what is the effect of co2 on photosynthesis?

Answer 1

co2 is combined with water(h2o) and light to make glucose(c6h12o6), for food. This is a little simplified.

Answer 2

CO2 is used into the making of glucose(I saw a good equation in one of the above answers) and so you can tell the more CO2 there is, the more the plant will photosynthesize.

However, should it lack another factor, say water, no matter how much CO2 you provide it with, it will still not photosynthesize.

If all factors are present, then the more CO2 you give, the more the pant will photosynthesize up to a point where if you're doing an experiment, you will realise the rate of photosynthesis will just reamin constant. This is because it is not a limiting factor anymore, another factor is,for example Intensity of the light or concentration of water or number of chloroplasts.

Answer 3

Photosynthesis combines carbon dioxide with water in order to build sugar.

Specifically, the carbon that makes up those sugar molecules comes from the carbon dioxide. After photosynthesis liberates the carbon from carbon dioxide, it releases the oxygen.

Thus, you have:

6 CO2 + 12 H20 + light --> C6 H12 O6 + 6 O2 + 6 H20

As you can see, the carbon dioxide is the source of carbon to build the glucose (sugar) molecule.

Answer 4

Animals breath out CO2 and breath in O2 the plants breath in CO2 and breath out O2, So the CO2 must be good for the plants.

Answer 5

co2 is used to fix carbon in the socalled 'dark reactions' (meaning light is not necessary for the reaction to occur, but the products of the light reaction are)
rubisco is the enzyme that is able to add the co2 to RUBP and then the cycle begins, and regenerates the RUBP to do it all again at the end
NOW THATS HOW ITS DONE
