Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or false:The light dependent reaction of photosynthesis uses energy to produce oxygen.
A
True
B
False
Explanation: 

Detailed explanation-1: -In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen from the hydrolysis of water as a byproduct.

Detailed explanation-2: -The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.

Detailed explanation-3: -In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide. Oxygen is released as a byproduct.

Detailed explanation-4: -The correct option is A True. During photosynthesis, Carbon dioxide(CO2) gas is taken in through stomata from the atmosphere. Oxygen(O2) gas is released through stomata into the atmosphere as a by-product.
