How are photosynthesis and cellular respiration inverses

They are inverses

Explanation:

Photosynthesis is the process of plants converting light energy into food, and letting out oxygen for humans to take in. We take in their oxygen and let out carbon dioxide to help them survive. So the formula for Photosynthesis would be carbon dioxide and water (plants need this to survive) makes oxygen and glucose

Cellular respiration is the process of taking food and breaking it down. It takes the chemical energy out of the food in our stomachs to create ATP. This occurs in the mitochondria, which is known as the powerhouse for this large role in human life. In cytology, we learned how vacuoles store waste products or foods, and transport them out of the cell. The vacuoles remove the waste products created by cellular respiration and remove them.

The formula for Cellular Respiration is oxygen and glucose (from food) turns into water and carbon dioxide.

i think it is true in my reasonment ..

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
