Solution

The statement is True.

In photosynthesis, particularly during the light reactions, chlorophyll absorbs light energy and uses it to excite electrons. As a result, these electrons are removed from chlorophyll and are transferred through a series of proteins in the thylakoid membrane in the chloroplasts. To replenish the electrons lost from chlorophyll, water molecules (H₂O) are split in a process known as photolysis. This process releases electrons, which then replace those lost by chlorophyll, thus maintaining the cycle of electron transport that is crucial for the production of ATP and NADPH during the light reactions of photosynthesis.

This overall process is essential for converting light energy into chemical energy in plants.
