What is the function of CO2 in photosynthesis? - Quora

The major work of evaporation of water is done by stomata.



Apart from the transpiration and photosynthesis process, stomata also have another very important function.

I will place a piece of cut pondweed into a beaker containing water and sodium hydrogen carbonate.

The word equation for photosynthesis is: Light [IMAGE]Carbon Dioxide + Water Glucose + Oxygen Chlorophyll Although most of the glucose produced is converted into insoluble starch for storage in the stem, leaves or roots, some is used immediately by the plant to provide via respiration....


what is the role of water in photosynthesis? | Yahoo Answers

As the plant takes water from the soil, the openings absorb other minerals.

Thus, in this process, six molecules of carbon dioxide and six molecules of water react in presence of sunlight to produce one molecule of glucose and six molecules of oxygen.

The final product of this process, i.e., glucose is stored in the complex molecular structure of the plant cells.


The important role of photosynthesis ..

Van Helmont believed that water was the source of the extra mass and the plant's source of life.

Repeat Helmont's experiment:





, a professor and physician at Cambridge University in the late 1600s, tried to design an experiment to test Van Helmont hypothesis that water was the source of the extra mass.

The primary function of photosynthesis is to convert solar ..

Photosynthetic organisms can be divided into two classes:those which produce oxygen and those which do not. Photosyntheticbacteria do not produce oxygen (in fact some of them calledanaerobes cannot tolerate oxygen) and this is considered a moreprimitive type of photosynthesis (in which the hydrogen donor ishydrogen sulfide, lactate or other compounds, but not water).Plants and one type of bacteria (cyanobacteria) do produceoxygen, an evolutionarily more advanced type of photosynthesis(in which the hydrogen donor is water).

Energy is released along with some carbon dioxide and water.

In a series of experiments over as many as 77 days, Woodward measured the water consumed by plants.

For example, one plant showed a mass gain of about 1 gram, while Woodward had added a total of almost 76,000 grams of water during the 77 days of plant growth - this was a typical result.

Plants take water and carbon dioxide and turn it into sugar

So the hypothesis that water is the nutrient used by plants was rejected.

Repeat John Woodward's experiment:




In August of 1771, , an English Chemist, put a sprig of mint into a transparent closed space with a candle that burned out the air (oxygen was not discovered yet) until it soon went out.
