|
Mass increases because high-energy chemical bonds have mass.
|
|
Mass remains the same because only the chemical bonds change.
|
|
Mass increases because light energy is converted into nuclear particles.
|
|
Mass remains the same because increased proton mass is offset by decreased electron mass.

Detailed explanation-1: -During photosynthesis, light provides energy for the reaction the converts water and carbon dioxide into oxygen and sugar. How does this conversion affect total mass of the matter involved in the reaction? Mass increases because high-energy chemical bonds have mass.
Detailed explanation-2: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Detailed explanation-3: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Detailed explanation-4: -The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH.
Detailed explanation-5: -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.
