prove that oxygen is necessary for photosynthesis
Answers
Answer:
because plants needed oxygen for her growth and the.. minerals reach all the plants
Answer:
By using the energy of sunlight, plants can convert carbon dioxide and water into carbohydrates and oxygen in a process calledphotosynthesis. 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.
Explanation:
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.
