C Plants require oxygen for photosynthesis and produce carbon dioxide. Plants then use the carbon dioxide produced in cellular respiration, releasing oxygen as a byproduct.
C Plants require oxygen for photosynthesis and produce carbon dioxide. Plants then use the carbon dioxide produced in cellular respiration, releasing oxygen as a byproduct.
The correct answer is C.
Plants require oxygen for photosynthesis, which is the process where plants use sunlight to convert carbon dioxide and water into glucose and oxygen. In this process, plants produce oxygen as a byproduct. The oxygen produced is then released into the environment through the plant's stomata or pores.
However, plants also require energy for growth, maintenance, and reproduction. To obtain this energy, plants undergo cellular respiration, a process similar to respiration in animals. During cellular respiration, plants use the glucose they produced in photosynthesis and combine it with oxygen from their surroundings to release energy. In this process, plants produce carbon dioxide as a byproduct. The carbon dioxide produced in cellular respiration is then used by the plant in photosynthesis, completing the cycle.
So, in summary, plants require oxygen for photosynthesis and produce carbon dioxide. Plants then use the carbon dioxide produced in cellular respiration, releasing oxygen as a byproduct.
Matter constantly cycles through the earth's spheres using many different processes. Photosynthesis and cellular respiration are two important processes in this cycling of matter. The products of photosynthesis are reactants in cellular respiration. The products of cellular respiration are the reactants of photosynthesis. This model shows the cycling of matter through these cycles. The model is unlabeled. Correctly label the products and reactants of cellular respiration. Choose to correct the three that apply.
Responses
A A = ATPA = ATP
B B = CO2 + H2OB = CO 2 + H 2 O
C A = C6H12O6A = C 6 H 12 O 6
D D = O2 + C6H12O6D = O 2 + C 6 H 12 O 6
E B = O2 + C6H12O6
The correct labels for the products and reactants of cellular respiration are:
B = CO2 + H2O (carbon dioxide and water)
C = C6H12O6 (glucose)
D = O2 + C6H12O6 (oxygen and glucose)
