why is oxygen needed for photosynthesis? | Yahoo Answers

Through reading various books and web pages it was made clear that carbon dioxide is definitely one of the raw materials needed for photosynthesis, but I wanted to see whether this is actually true and if carbon dioxide is taken away completely will the plant photosynthesize at all.

For photosynthesis to occur, plants need sunlight, water, carbon dioxide and chlorophyll

So how can these factors have an effect on the rate of photosynthesis? Lets start off with the light intensity. When the light intensity is poor, there is a shortage of ATP and NADPH, as these are products from the light dependent reactions. Without these products the light independent reactions can't occur as glycerate 3-phosphate cannot be reduced. Therefore a shortage of these products will limit the rate of photosynthesis. When the carbon dioxide concentration is low, the amount of glycerate 3-phosphate produced is limited as carbon dioxide is needed for its production and therefore the rate of photosynthesis is affected. Finally, many enzymes are involved during the process of photosynthesis. At low temperatures these enzymes work slower. At high temperatures the enzymes no longer work effectively. This affects the rate of the reactions in the Calvin cycle and therefore the rate of photosynthesis will be affected.

and which is needed by plants for photosynthesis

Plants need to be adapted so that maximum light energy is absorbed and therefore maximum photosynthesis occurs.

For photosynthesis to occur, plants need: · Light energy from the sun · Chlorophyll to absorb light energy · Carbon dioxide from the atmosphere and from respiration in plant cells · Water which is absorbed by the roots and transported to the leaves by the xylem tubes....

Temperature, carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis.Plants also need mineral ions, including nitrate and magnesium, for healthy growth.

Experiment to show that carbon dioxide is needed for photosynthesis

According to formula, what is needed for photosynthesis?

Below are things that plants need for photosynthesis:

Carbon dioxide (A colorless, naturally occurring odorless gas found in the air we breathe. It has a scientific symbol CO2. CO2 is produced by burning carbon and organic compounds. It is also produced when plants and animals breathe out during respiration)


Light (Even though both natural and artificial light is OK for plants, natural sunlight is usually great for photosynthesis because they have other natural UV properties that help the plant)

Chlorophyll (This is the green pigment found in the leaves of plants)

Nutrients and minerals (Chemicals and organic compounds which the plant roots absorb from the soil)

The further away the light, the slower the oxygen bubbles will be produced so the less light the less photosynthesis will occur which is needed for the plant to make food....

PHOTOSYNTHESIS - Estrella Mountain Community …

Photosynthesis is the process used by plants to convert electromagnetic radiation – light – into chemical energy that is used for growth and development. All that is needed for this process is carbon dioxide (CO2), nutrients, and water. The process itself is not particularly efficient; only 4 to 6 percent of the absorbed radiation is converted into chemical energy (Zhu et al. 2010, Table 2). Still, it is the engine that drives most life on this planet.

an energy carrier needed in the Light Independent Reaction.

Plants can turn the glucose produced in photosynthesis into starch for storage, and turn it back into glucose when it is needed for respiration. for storage.

We, in turn, exhale the carbon dioxide needed by plants.

For illumination engineers, it might seem suspicious that the photosynthetically active radiation is defined over the spectral range 400 nm to 700 nm – exactly the range we commonly assume for human vision. What about longer and shorter wavelengths?
