Question 1 Report

The oxygen released during photosynthesis is obtained
Answer Details
During photosynthesis, oxygen is released as a byproduct when water molecules are split into hydrogen ions and oxygen atoms through a process called photolysis. This occurs in the chloroplasts of plant cells, where chlorophyll traps light energy from the sun and converts it into chemical energy used to power the process of photosynthesis. Thus, the correct answer is: "During the photolysis of water using energy trapped in chlorophyll".
