EVERYDAY SCIENCE

Detailed explanation-1: -The solar energy is converted into chemical energy during photosynthesis. The leaves have a green pigment called chlorophyll. It helps leaves to capture the energy of the sunlight. This energy is used to synthesise food from carbon dioxide and water.

Detailed explanation-2: -During photosynthesis, chlorophyll absorbs energy from blue-and red-light waves, and reflects green-light waves, making the plant appear green. While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.

Detailed explanation-3: -Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

Detailed explanation-4: -Most solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants.
