Write the name of process in which the plants produce oxygen:
Answers
Answer:
PHOTOSYNTHESIS
Explanation:
Answer:
Answer 1:
By using the energy of sunlight, plants can convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. As photosynthesis requires sunlight, this process only happens during the day. We often like to think of this as plants `breathing in carbon dioxide and `breathing out oxygen. However, the process is not exactly this simple. Just like animals, plants need to break down carbohydrates into energy. Oxygen is required to do this. Then why do the plants get rid of all the oxygen they produce during photosynthesis? The answer is, they do not. Plants actually hold on to a small amount of the oxygen they produced in photosynthesis and use that oxygen to break down carbohydrates to give them energy.
But what happens at night when there is no sunlight which is needed in photosynthesis? Interestingly, in order to maintain their metabolism and continue respiration at night, plants must absorb oxygen from the air and give off carbon dioxide (which is exactly what animals do). Fortunately for all of us oxygen breathers, plants produce approximately ten times more oxygen during the day that what they consume at night.
Answer 2:
Plants break down sugar to energy using the same processes that we do. Oxygen is needed to break the sugar into carbon dioxide, releasing energy the plants can use to stay alive.
However, plants also take in energy from the sun(light), carbon dioxide from the atmosphere, and water from the soil; they use all of them in order to make sugar, and release oxygen. (They use the 'carbon' in carbon dioxide to build the sugar molecule). Since there's no sunlight at night, this gives the plants a way to stay alive, even when there's no light.
However, plants use sugar to build pretty much everything! Cellulose, the hard stuff in plants, is just a bunch of sugar molecules linked together. We can't digest it though, but some animals can. Similarly, plants make starch (sugar linked together, but not as tightly) to store energy for when it's dark. We're able to digest starch.
Since the plants use the sugar they make for more than just energy, they produce more oxygen than they use.
Answer 3:
Great question! Plants produce oxygen, because when they photosynthesize, they take carbon dioxide (CO2; a gas-form of carbon bonded to two oxygen molecules) and water (H2O; an oxygen bonded to two hydrogen atoms) and combine them using light energy to produce sugars and oxygen. This stores the energy in chemical bonds (in the sugars) and releases O2. The chemical equation for this is:
6CO2 + 6H2 C6H12O6(sugar) + 6O2
