light absorption
The first simple food prepared in the process of photosynthesis is glucose. Glucose is synthesized from carbon dioxide and water using energy from sunlight during the light-dependent reactions of photosynthesis.

Light Dependant Reactions
The first process in the light-dependent reactions of photosynthesis is photon absorption by chlorophyll molecules in the thylakoid membrane of the chloroplast. Absorbed photons then excite electrons in chlorophyll, initiating the transfer of these high-energy electrons through a series of protein complexes known as the electron transport chain.
cell wall
This is called the light phase oh photosynthesis as opposed to the dark phase. During the light phase, photons excite enzymes on the thylakoid. Also can be known as Light-Dependent Reactions
Chemical reactions like chemosynthesis, where organisms convert inorganic compounds into energy using chemical reactions instead of light, are similar to photosynthesis. Both processes involve the conversion of energy into a usable form for the organism's growth and survival.
The light dependent and the light independent reactions.
No, the light-dependent reactions in photosynthesis cannot occur without the light-independent reactions. The light-dependent reactions, which take place in the thylakoid membranes of chloroplasts, require light energy to produce ATP and NADPH. These molecules are then used in the light-independent reactions (Calvin cycle) to convert carbon dioxide into glucose. Thus, both sets of reactions are interdependent and necessary for the complete process of photosynthesis.
The first pathway of photosynthesis is the light reaction, which is the absorption of light energy from the sun by the chlorophyll in the plant. The pathway that follows this is the dark reaction or carbon fixation.
The light-dependent reactions, or light reactions, are the first stage of photosynthesis. In this process light energy is converted into chemical energy, in the form of the energy-carriers ATP and NADPH. In the light-independent reactions, the formed NADPH and ATP drive the reduction of CO2 to more useful organic compounds, such as glucose.
