DENDROLOGY

Detailed explanation-1: -Answer and Explanation: The stage of photosynthesis during which chlorophyll absorbs light energy is called the light dependant reaction. During the light dependant reaction a plant is able to absorb the energy present from the sun and convert it into chemical energy.

Detailed explanation-2: -During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules.

Detailed explanation-3: -The first step of photosynthesis is the absorption of light energy and the loss of electrons from chlorophyll. Photosynthesis is a process by the plant to produce food by absorbing light of a certain wavelength and used to convert water and carbon dioxide and minerals into oxygen-rich and energy-rich organic compounds.

Detailed explanation-4: -The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light-dependent reaction. The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH.
