Detailed explanation-1: -If carbon dioxide is completely removed from a plant’s environment, we would expect the plant to stop producing high-energy sugars altogether. CO2 is necessary for the plant to perform photosynthesis, meaning without CO2 the plant has no way to obtain energy-it will likely die in this scenario.
Detailed explanation-2: -’12 The most likely result of completely removing carbon dioxide from the environment of a plant is that sugar production will continue at the Same rate inerease and oxygen procuction will also in-crease inerease and oxygen production will stay the SaC decrease and eventually stop’
Detailed explanation-3: -The same number of sugars will be produced but without carbon dioxide. Carbon dioxide does not affect the production of high-energy sugars in plants.
Detailed explanation-4: -Through a process called photosynthesis, leaves pull in carbon dioxide and water and use the energy of the sun to convert this into chemical compounds such as sugars that feed the tree. But as a by-product of that chemical reaction oxygen is produced and released by the tree.
Detailed explanation-5: -Carbon dioxide and rate of photosynthesis An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor.
