Photosynthesis and cellular respiration are processes that create for the cell.

Both processes create energy. Photosynthesis creates glucose (energy from the sun is converted to chemical energy) and oxygen for the cell while cellular respiration creates energy for the cell.

Explanation: Photosynthesis and cellular respiration are two important processes. Photosynthesis occurs only in plants while cellular respiration occurs in both plants and animals.

In photosynthesis, plants use carbon dioxide, water and sunlight to produce glucose and oxygen while in cellular respiration both plants and animals breakdown glucose in the presence of oxygen to produce carbon dioxide, water and energy. The light energy conserved in glucose during photosynthesis is broken down during cellular respiration to release chemical energy.

The chemical equation for photosynthesis is 6CO2+ 6H2O + sunlight --> C6H12O6 + 6O2.

The chemical equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy. The energy produced in cellular respiration is used to carry out other cellular processes.

Photosynthesis occurs in the chloroplast which is an organelle found only in plant cells while cellular respiration occurs in the mitochondria.

Photosynthesis uses carbon dioxide and water produced in cellular respiration while cellular respiration uses glucose and oxygen produced in photosynthesis. This means that the two processes depend on each other for the supply of its reactants.
