Why oxygen is evolved during photosynthesis ? what makes water to evolve oxygen? explain please?

Question

Answer

To prove that oxygen is produced during photosynthesis following steps need to do
Place water plant in a beaker containing pond water.
Cover the plant with short stemmed funnel.
Invert the test tube full of water and cover the stem of the funnel.
While placing the test tube, ensure that the level of the water in beaker is above the level of stem of funnel.
Expose the apparatus to the sunlight.
After few hours, gas bubbles will form and collect in the test tube.
Test the gas in the test tube.
A glowing splinter bursts into the flame shows the presence of oxygen.
Observation: Gas bubbles in a test tube.
Result: Presence of oxygen.
Conclusion: Formation of gas bubbles prove that oxygen is produced by the green plants during photosynthesis.

Plants break down sugar to energy using the same processes that we do. Oxygen is needed to break the sugar into carbon dioxide, releasing energy the plants can use to stay alive

Answer

Oxygen evolution in nature

It utilizes the energy of light to split a water molecule into its protons and electrons for photosynthesis. ... 2H2O ⟶ 4e− + 4H+ + O. The protons are released into the thylakoid lumen, thus contributing to the generation of a proton gradient across the thylakoid membrane.

Answer

Answer

During photosynthesis the plants absorbs water and carbon dioxide. After the absorption, the water molecules are disassembled and converted into sugar and oxygen. The water molecules are also split into oxygen and hydrogen and latter (hydrogen) is joined to the carbon dioxide to create sugar

Answer

The reaction is part of the light-dependent reactions ofphotosynthesis in cyanobacteria and the chloroplasts of green algae and plants. It utilizes the energy of light to split a water molecule into its protons and electrons for photosynthesis. ..

. 2H2O = 4e− + 4H+ + O.

Answer

Introduction:
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. Oxygen is evolved as a by-product during this process. The process of oxygen evolution during photosynthesis involves the splitting of water into hydrogen ions and oxygen.

Chloroplasts:
The process of photosynthesis takes place in specialized organelles called chloroplasts which are present in the leaves of plants. Chloroplasts contain chlorophyll pigments which absorb light energy from the sun.

Light-Dependent Reactions:
Photosynthesis is a two-step process. In the first step, called the light-dependent reactions, light energy is converted into chemical energy in the form of ATP and NADPH. During this step, water molecules are split into oxygen, hydrogen ions, and electrons. The oxygen is released into the atmosphere as a byproduct.

Water Splitting:
The splitting of water molecules into oxygen and hydrogen ions is a complex process that involves the transfer of electrons. The process is carried out by a complex of proteins and pigments called the photosystem II complex. The complex absorbs light energy and uses it to split water molecules into oxygen, hydrogen ions, and electrons.

Oxygen Evolution:
Once the water molecules are split, the oxygen is released into the atmosphere. The oxygen is a byproduct of photosynthesis and is essential for life on Earth. The oxygen released during photosynthesis is responsible for maintaining the oxygen levels in the atmosphere.

Conclusion:
In conclusion, oxygen is evolved during photosynthesis as a byproduct of the splitting of water molecules. The process of oxygen evolution is carried out by a complex of proteins and pigments called the photosystem II complex. The oxygen released during photosynthesis is essential for life on Earth.

Answer

During photosynthesis the plants absorb carbon dioxide and water
cloroplast absorb sunlight
clorophyll changes light energy into chemical energy
this chemical energy splits into hydrogen and oxygen
