The essential process connected with photosynthesis is:A: Photolysis of waterExplanation:Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy into chemical energy in the form of glucose or other sugars. There are several processes involved in photosynthesis, and one of the crucial steps is the photolysis of water.- Photolysis of water: Also known as the light-dependent reaction or water-splitting reaction, this process occurs in the thylakoid membrane of the chloroplasts. It involves the absorption of light by photosystem II, which excites electrons and leads to the splitting of water molecules. The breakdown of water produces oxygen gas (O2), which is released as a byproduct, as well as hydrogen ions (H+) and electrons that are used in the next steps of photosynthesis.- Importance of photolysis: The photolysis of water is essential for photosynthesis because it provides the necessary electrons and protons for the production of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). Both ATP and NADPH are essential energy carriers that are required for the light-independent reactions, also known as the Calvin-Benson cycle, during which carbon dioxide is fixed, and glucose is synthesized.The other options mentioned (B, C, and D) are also related to photosynthesis, but they are not as essential as the photolysis of water:- B: Synthesis of glucose: This is the ultimate goal of photosynthesis, but it is not an essential process directly connected to the light-dependent reactions. Glucose synthesis occurs during the light-independent reactions (Calvin-Benson cycle).- C: Breakdown of glucose: This is related to cellular respiration rather than photosynthesis. The breakdown of glucose provides energy for the cell, but it is not an essential process directly connected to photosynthesis.- D: Photophosphorylation: This is the process by which ATP is produced during the light-dependent reactions of photosynthesis. While it is an essential process for producing the energy needed for the light-independent reactions, it is not as directly connected to photosynthesis as the photolysis of water.

Photosynthesis is the process by which green plants and some other organisms convert light energy into chemical energy. It involves the synthesis of glucose from carbon dioxide and water in the presence of sunlight and chlorophyll. The process takes place in two stages: the light-dependent reactions and the light-independent reactions.
One of the essential processes connected with photosynthesis is photolysis of water. This process occurs in the thylakoid membranes of chloroplasts during the light-dependent reactions. It involves the splitting of water molecules into hydrogen ions, electrons, and oxygen gas.
The photolysis of water is a crucial step in the photosynthetic process because it provides the electrons and hydrogen ions required for the synthesis of ATP and NADPH, which are energy-rich molecules that drive the light-independent reactions. The oxygen gas produced during photolysis is released into the atmosphere as a byproduct of photosynthesis.
In summary, photolysis of water is an essential process connected with photosynthesis because it provides the electrons and hydrogen ions needed for the synthesis of ATP and NADPH, which are energy-rich molecules that drive the light-independent reactions. The oxygen gas produced during photolysis is released into the atmosphere as a byproduct of photosynthesis.
