Question

Quizplus · Accepted Answer

Photosynthesis is the process by which green plants and other organisms convert light energy into chemical energy in the form of glucose. During photosynthesis, oxygen is released as a byproduct and is released into the atmosphere. Therefore, choice A is the correct answer. Choice B is incorrect because photosynthesis does not release carbon dioxide, it actually uses it as a raw material. Choice C is incorrect because photosynthesis is primarily carried out by green plants and algae, not bacteria. Choice D is incorrect because photosynthesis did not occur until much later in the earth's history when photosynthetic organisms evolved.
