Detailed explanation-1: -True or false: light energy is changed to cell energy in stage 1 of photosynthesis. False it changes to cell energy in stage 2 of photosynthesis.
Detailed explanation-2: -Step 1. The first step of photosynthesis is Light-dependent. The three main components of this step are water, carbon dioxide, and sunlight. Carbon Dioxide and water enter the leaf, and the sunlight is absorbed to produce energy in the whole process.
Detailed explanation-3: -During the process of photosynthesis, light energy is converted to chemical energy.
Detailed explanation-4: -Chlorophyll, a green pigment found in chloroplasts, is an important part of the light-dependent reactions. Chlorophyll soaks up the energy from sunlight. It is also the reason why plants are green.
Detailed explanation-5: -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.
