Photosynthesis and cellular respiration are related in that; photosynthesis is a process that is tasked in making glucose which is then used in cellular respiration to make ATP. The glucose is then converted to carbon dioxide during cellular respiration, which is used in photosynthesis. Water on the other hand is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
The answer is A: Polyploidy is a condition in which an organism acquired more than the normal amount of chromosomes.
Hope this helps.
During the day, due to the presence of sunlight, the process of photosynthesis peaks over that of respiration. Photosynthesis uses carbon dioxide to make carbohydrates releasing oxygen as a byproduct. During the night, because there is no sunlight, the rate of photosynthesis drops. This, therefore, causes the rate of respiration to surpasses the rate of photosynthesis. In respiration, oxygen is consumed and carbon dioxide is released.
