Why do plants perform photolysis splitting of water )?
Water is absolute requirement for photosynthesis to occur. During Light reactions of Photosynthesis, the chlorophyll will be activated by light. This light activated chlorophyll will split the water molecule. This process is called Photolysis.
Why does photolysis of water occur during daytime?
Photolysis of water takes place in the light phase. Light phase is a part of photosynthesis during which oxygen is released. Thus, this whole process of photolysis of water takes place during the light phase of photosynthesis. Thus option C is the correct answer.
Does photolysis happen in plants?
Photolysis of water occurs in the thylakoids of cyanobacteria and the chloroplasts of green algae and plants.
Where does photolysis of water takes place in plants?
The photolysis of the water in plants takes place in the grana of the chloroplast. – During the light phase of the plant,the excessive water (H2O) is dissociated into hydrogen and oxygen which is known as the photolysis of the water.
How does photolysis of water occur?
Photolysis of water: Photolysis of water means the splitting of water molecules in the presence of light or photons into hydrogen ions, oxygen and electrons. – Photolysis of water occurs in the chloroplasts of plants. It also occurs in the thylakoids of cyanobacteria (blue-green algae).
Why is water split during photosynthesis quizlet?
The oxygen released during photosynthesis comes from the splitting of water during the light-dependent reaction. 3. Remember, the electrons lost from the reaction center in photosystem II must be replaced. The splitting of water serves to replace these lost electrons.
What happens in photolysis of water?
This part of photosynthesis occurs in the granum of a chloroplast where light is absorbed by chlorophyll; a type of photosynthetic pigment that converts the light to chemical energy. This reacts with water (H2O) and splits the oxygen and hydrogen molecules apart.
Why is the photolysis of water essential in photosynthesis?
Water Photolysis Water acts as a reducing agent by providing H+ ions that convert NADP to NADPH. Since NADPH is an important reducing agent present in chloroplasts, its production results in a deficit of electrons, resulting from oxidation of chlorophyll.
What is photolysis of water in plants?
What will happen if there is no splitting of water in photosynthesis?
When water molecules split during the photosynthetic reaction, oxygen molecules are formed and released into the water and air. Without oxygen, life would not exist as it does today.
What would happen if water was not available for photosynthesis?
Plants need nutrients from the soil, water, and light from the sun to grow and stay alive. If plants did not get water, they would die. The two main things plants need water for are turgor, to keep the upright and make sure it doesn’t wilt and for photosynthesis.
What is the importance of photolysis of water during photosynthesis?
Explanation: The chemical procedure by which plants and some organisms, using sunlight, produce nutrients from and is known as Photosynthesis. Therefore photolysis plays an important role in photosynthesis, during which it produces energy by splitting water molecules into gaseous oxygen and hydrogen ions.
