Sentences 1 and 3 tell us that plant cells take in carbon dioxide and water, which are the reactants used during photosynthesis. Sentence 2 tells us that plants are autotrophs, which means they make their own food.
Read the following passage. This is an exercise in careful reading, so make sure to read the passage carefully. Plants perform photosynthesis in order to rearrange atoms from carbon dioxide and water to form glucose and oxygen gas. Because the glucose can be used as a food source for the plants, plants are known as autotrophs. The reaction that occurs in photosynthesis is represented by this equation: 6CO2 + 6H2O →C6H12O6 + 6O2. Photosynthesis occurs in specialized organelles, called chloroplasts, in the cells of green plants. Here is the same passage, but it has the sentences numbered this time. 1Plants perform photosynthesis in order to rearrange atoms from carbon dioxide and water to form glucose and oxygen gas. 2Because the glucose can be used as a food source for the plants, plants are known as autotrophs. 3The reaction that occurs in photosynthesis is represented by this equation: 6CO2 + 6H2O →C6H12O6 + 6O2. 4Photosynthesis occurs in specialized organelles, called chloroplasts, in the cells of green plants.
