What is the difference between grana and stroma thylakoids ?
Could you also give me an example showing that photosynthesis is the reverse of respiration ? Thank you

a grana is a stack of multiple thylakoids.

For your second question, just look at the chemical equation for photosynthesis and cell respiration and you'll find that they are almost exact opposites.
Photsynthesis: 6CO2 + 6H2O + LIGHT ENERGY--> C6H12O6 + 6O2
Respiration: C6H12O6 + 6O2--> 6CO2 + 6H2O + ENERGY RELEASED (ATP
