Question

State whether the following statement is True or False. It False, rewrite the correct form of the statement by changing the first or the last word only.

Photolysis is the process of splitting of water molecules in the presence of grana and temperature.

• A. True
• B. False

Answer 1

The correct option is B False

Photolysis:

1. It is the process of splitting water molecules in the presence of grana and sunlight.
2. Photolysis is the process of splitting water (H₂O) into hydrogen (H⁺) and hydroxyl (OH^-) ions.
3. The photochemical phase or light reaction and dark or biosynthetic phase are two main stages of photosynthesis. Photolysis of water takes place in the photochemical phase of photosynthesis and in the grana of the chloroplast. light is essential for the photochemical phase.
4. Granum (plural., Grana) is a stack of coin-shaped thylakoids present in chloroplasts of plant cells. The shape of thylakoids, stacked in the grana allows for maximum surface area and maximizes the process of photosynthesis.

Final answer: The above statement is False.
