Yes, and no. It is when the plant takes in sunlight, and changes it in to energy, so it gains energy, and releases oxygen.
The process is called Photosynthesis.
The energy is not releasing. it is storing in photosynthesis.
Photosynthesis makes glucose molecules, but cellular respiration breaks them down.
The process is respiration (cellular respiration). It breaks down the compounds called carbohydrates to release the energy stored there (which almost always originally came from photosynthesis).
The process by which plants make energy is called Photosynthesis.
Anareobic Respiration photosynthesis( the previous answer) does require oxygen, Anareobic means it does not require oxygen.
During the process of photosynthesis, light energy is converted to chemical energy.
The Energy releasing process that would be best is cellular resperation because it is the only process in our cells that release the most Energy. :D
Cellular photosynthesis
Respiration.
Photosynthesis is the cellular process that converts solar energy into chemical energy.
The sun's energy is converted into food by the process of photosynthesis.
