Question

Explain the process of photosynthesis in plants giving the mechanism of light reaction and the process of dark reaction.
​

Answer 1

Explanation:

Photosynthesis: is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy.  

Photosynthesis: is a chemical process through which plants, some bacteria and algae, produce glucose and oxygen from carbon dioxide and water, using only light as a source of energy.  This process is extremely important for life on earth as it provides the oxygen that all other life depends on.

They are initiated by colored pigments, mainly green colored chlorophylls.

This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma.ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.

Answer 2

Explanation:

Photosynthesis - The process in which green plants convert simple inorganic substances like CO2 and H2O into complex organic substance glucose in the presence of sunlight and chlorophyll.

Mechanism of photosynthesis

Light phase - (i) Absorption of sunlight by

chlorophyll

(ii) Conversion of light energy into

chemical and splitting of water

molecules into H2 & O2

(iii) Reduction of NADP (NADP + H2)

Dark phase - (iv) Break down of NADP + H2 using ATP

(v) Reduction of CO2

Note - Light phase is called light phase as it occur in the presence of sunlight.

Dark phase is called dark phase as it do not require sunlight ( it can occur in day time also )
