True
In the process of photosynthesis, plants convert carbon dioxide and water into glucose and oxygen using sunlight. The equation for photosynthesis can be summarized as:
\[ \text{6 CO}_2 + \text{6 H}_2\text{O} + \text{light energy} \rightarrow \text{C}6\text{H}{12}\text{O}_6 + \text{6 O}_2 \]
In cellular respiration, the process is essentially the reverse, where glucose and oxygen are converted back into carbon dioxide and water to release energy. The equation for cellular respiration is:
\[ \text{C}6\text{H}{12}\text{O}_6 + \text{6 O}_2 \rightarrow \text{6 CO}_2 + \text{6 H}_2\text{O} + \text{energy (ATP)} \]
Thus, the reactants of cellular respiration (glucose and oxygen) are indeed the products of photosynthesis (glucose and oxygen), making the statement true.
