Does photosynthesis produces carbon dioxide gas?

Close to lower epidermis allowing rapid diffusion of gases into and out of leaf.
In the stroma, the light-independent (Calvin cycle) photosynthetic reactions take place- the bonding of carbon dioxide with hydrogen (from water), and their rearrangement to form glucose, CHO
Chloroplasts are also found in the outer layer of cells (cortex) in the stems of non-woody plants.

Chlorophyll in plant leaves converts carbon dioxide and water into the products glucose and oxygen.

That's right. The plant would not grow. It is true that a plant needs to take in carbon dioxide in order to survive and that it expels oxygen as the waste product of photosynthesis. But a plant doesn't only store the food it produces—it uses some to feed itself. And when a plant feeds on its own food, that food is broken down in the same way that it's broken down in an animal's body (including yours): with oxygen. The oxygen is needed to break down the carbohydrate molecules and release the energy stored in those molecules.

gas exchange (exchange of oxygen and carbon dioxide ..

Plants' consumption of carbon dioxide, and production of oxygen by photosynthesis, is what creates our life-sustaining atmosphere.

The answer is actually "no, a plant could not grow without oxygen." Perhaps you're thinking that a plant needs to take in carbon dioxide in order to survive and that it expels oxygen as the waste product of photosynthesis. This is certainly true. But a plant doesn't only store the food it produces—it uses some to feed itself. And when a plant feeds on its own food, that food is broken down in the same way that it's broken down in an animal's body (including yours): with oxygen. The oxygen is needed to break down the carbohydrate molecules and release the energy stored in those molecules.

By using the energy of sunlight, plants canconvert carbon dioxide and water intocarbohydrates and oxygen in a process calledphotosynthesis. As photosynthesis requiressunlight, this process only happens during theday. We often like to think of this as plants`breathing in carbon dioxide and `breathing outoxygen. However, the process is not exactly thissimple. Just like animals, plants need to breakdown carbohydrates into energy. Oxygen is requiredto do this. Then why do the plants get rid of allthe oxygen they produce during photosynthesis? Theanswer is, they do not. Plants actually hold on toa small amount of the oxygen they produced inphotosynthesis and use that oxygen to break downcarbohydrates to give them energy.

gas exchange between oxygen and carbon dioxide occurs and the end ..

No, it produces sugars and gives off oxygen: Respiration gives off carbon dioxide.

Photosynthesis sure is a miracle, isn't it? It allows plants, bacteria, and algae to take carbon dioxide and, with the help of a little sunlight, turn it into the oxygen we all breathe. But now scientists have taken photosynthesis out of the equation and have managed to make oxygen (O2) by zapping carbon dioxide (CO2) with a laser.

Plants produce oxygen as a waste product ofmaking sugar using sunlight, carbon dioxide, andwater. If a plant needs energy, but doesn't havesunlight, then it can burn the sugar that it madeback when it had sunlight, and doing so requiresoxygen.

So, the conventional wisdom has been that under almost all circumstances, it'd be impossible to take carbon dioxide—say, from a human's exhalation, for instance—and turn it back into gaseous oxygen, which would require two oxygen atoms. But then, researchers at the University of California, Davis decided to try doing just that by exciting carbon dioxide using what's known as a "high energy vacuum ultraviolet laser."

16/06/2002 · Photosynthesis and respiration ..

The oxygen produced in photosynthesis comes from water because this is the molecule in which a bond is broken by sunlight to separate charge allowing synthesis of molecules with reducing power and energy transfer potential. Carbon dioxide is the building block of the sugar and far from breaking a C=O bond, what is needed is for it to be reduced to C-OH.

produces carbon dioxide in return

In words, this equation states that sunlight, combined with six molecules of water (H2O) and six molecules of carbon dioxide (CO2), produces one molecule of sugar (C6H12O6) and six molecules of oxygen gas (O2).

through carbon dioxide being turned ..

Plants can do two importantthings:
Use energy from the sun to turnCO2 (carbon dioxide) and H2O(water) into sugar(C6H12O6) withoxygen (O2) left over. This isphotosynthesis.

What Are the Products of Photosynthesis? - ThoughtCo

Great question! Plants produce oxygen, becausewhen they photosynthesize, they take carbondioxide (CO2; a gas-form of carbonbonded to two oxygen molecules) and water(H2O; an oxygen bonded to two hydrogenatoms) and combine them using light energy toproduce sugars and oxygen. This stores the energyin chemical bonds (in the sugars) and releasesO2.The chemical equation for thisis:6CO2 + 6H2C6H12O6(sugar) +6O2
