Answer
To answer the question, let's analyze each statement in relation to the processes of photosynthesis and cellular respiration:1. The reactants and products of both processes are the same. - This statement is incorrect. The reactants of photosynthesis are carbon dioxide and water, and the products are glucose (a carbohydrate) and oxygen. The reactants of cellular respiration are glucose and oxygen, and the products are carbon dioxide, water, and ATP. While there is an overlap (oxygen and glucose are products of photosynthesis and reactants of cellular respiration), they are not the same for both processes.2. Photosynthesis and cellular respiration occur in all organisms. - This statement is incorrect. Photosynthesis occurs in plants, algae, and some bacteria that contain chlorophyll or a similar pigment. Cellular respiration occurs in almost all organisms, including plants, animals, fungi, and many bacteria, but not all organisms can perform photosynthesis.3. Products of photosynthesis form the reactants for cellular respiration. - This statement is correct. The glucose and oxygen produced during photosynthesis are used as reactants in cellular respiration to produce ATP.4. All ATP produced during photosynthesis is utilized during cellular respiration. - This statement is incorrect. ATP produced during photosynthesis is used for various processes within the plant cells, not just cellular respiration. Additionally, ATP is produced during cellular respiration, but not all of it is necessarily derived from the ATP produced in photosynthesis.Based on the analysis, the correct statement that describes the relationship between photosynthesis and cellular respiration is:Products of photosynthesis form the reactants for cellular respiration.
