Respiration is how animal cells get their energy to preform their necessary functions. Plant cells don't use respiration, because they use photosynthesis. Photosynthesis turns light into energy.
Tid-bit of info:
Cellular Respiration Formula: 
Sugar + Oxygen = Carbon Dioxide + Water <span>+ ATP </span>
C₆H₁₂O₆ + O₂ = CO₂ + H₂O <span>+ ATP </span>
Photosynthesis Formula: 
Sunlight + Water + Carbon Dioxide = Oxygen + Sugar
Sunlight + H₂O + CO₂ = O₂ + C₆H₁₂O₆
