why do plants release oxygen and not carbon dioxide

Answer 4: The quick answer to your question is that
oxygen is just a waste product when plants do photosynthesis. ) left over. This is photosynthesis. O (water), but they need (O ) oxygen to do it. This is cellular respiration. We can only do the second thing. The first law of thermodynamics tells us that matter cannot be created or destroyed. It cannot come from nothing and it cannot disappear. So the same number of atoms (C, H, O) have to enter and leave. Let us write photosynthesis as a balanced equation. Count up the number of carbon atoms on each side of the arrow.

If you have six on one side, you need six on the other. Now count the hydrogen atoms. (6 X 2) on one side and 12 on the other. How many oxygen atoms are on the left side? (6 X 2) + (6 X 1) = ___. Now how many oxygen atoms are in the glucose? 6. So you have oxygen atoms left over. That is where the O comes from. It is the left over material from making sugar. Just like when you make something, the scraps you cut off do not disappear. The plant breathes out the oxygen, which is good for all of us animals because we need oxygen, as you know.

Could there be animals without plants? Could there be plants without animals? photosynthesis The chemical change that occurs in the leaves of green plants. It uses light energy to convert carbon dioxide and water into glucose. Oxygen is produced as a by-product of photosynthesis. is a chemical reaction that happens in the chloroplasts of plant cells. It produces glucose for use by the plant, and oxygen as a waste product. Here are the equations for photosynthesis: O P chloroplast Microscopic structure containing chlorophyl found in green plant cells where photosynthesis takes place. for photosynthesis to happen. respire To engage in respiration - the energy-producing process inside living cells plants carry out respiration as well.

Plants respire all the time because their cells need energy to stay alive, but plants can only photosynthesise when they are in the light. The diagrams summarise what this means for the overall release of carbon dioxide or oxygen from plants. Remember that respiration uses oxygen and produces carbon dioxide.
