What is photosynthesis?
The synthesis of complex organic compounds from simple organic compounds like water and carbondioxide by green plants in the presence of chlorophyll using sunlight is called photosynthesis.

Differentiate between cyclic and non-cyclic photophosphorylation.
Differences between cyclic and non-cyclic photophosphorylation are given below:-
cyclic photophosphorylation | non-cyclic photophosphorylation |
1. In this process, electron released from the reaction centre passes through different different ways and return back to the same centre. 2. Only PSI system is involved in it. 3. Last electron acceptor in it is P₇₀₀ (PSI) itself. 4. It produces ATP only. 5. First electron donor in it is P₇₀₀. 6. It takes place in all plants and bacteria. | 1. In this reaction, electron released by the reaction centre doesn't return back to the same centre. 2. Both PSI and PSII systems are involved in it. 3. Last electron receptor in it is NADP. 4. It produces ATP, NADPH₂ and O₂. 5. First electron donor in it is water. 6. It takes place in all plants but absent in bacteria. |
