Detailed explanation-1: -To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Detailed explanation-2: -They capture the sun’s energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.
Detailed explanation-3: -Photosynthetic cells contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose.
Detailed explanation-4: -Photosynthesis involves two stages: the light-dependent reactions, which require sunlight and water to produce oxygen, ATP, and NADPH, and the light-independent reactions (or “dark reactions"), which use the products of the light-dependent reactions along with carbon dioxide to produce carbohydrates.
