Which is the relationship between photosynthesis and cellular respiration?

cellular respiration makes the glucose that is needed by photosynthesis.

photosynthesis makes the glucose that is broken down by cellular respiration.

cellular respiration converts the glucose that is made by photosynthesis to oxygen.

photosynthesis converts the glucose that is made by cellular respiration to carbon dioxide.

The correct answer would be  "Photosynthesis makes the glucose that is broken down by cellular respiration".

Photosynthesis is the process by which autotrophs or green plants synthesize their food (glucose) from carbon dioxide and water with the help of chlorophyll and sun.

They convert solar energy into chemical energy (food) and oxygen is released  as the byproduct.

6CO₂ + 6H₂O + solar energy → C₆H₁₂O₆ + 6O₂

In contrast, cellular respiration refers to the set of metabolic reactions which harnessed the chemical energy of food or glucose and convert it into ATP (adenosine triphosphate), the energy currency of the cell.

The cell requires oxygen for the complete oxidation of the food or glucose.

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
