Detailed explanation-1: -Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).

Detailed explanation-2: -Photosynthesis is the process in which plants collect radiant energy (from the Sun) and transform it into chemical energy. The chemical energy is stored in the plant as sugar and is available as food. The leaves of plants contain everything needed to absorb the rays of the Sun and start photosynthesis.

Detailed explanation-3: -The Two Parts of Photosynthesis Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.

Detailed explanation-4: -In photosynthesis, chemical energy is converted to light energy.

Detailed explanation-5: -Solar energy is converted into chemical energy during photosynthesis.
