Honors Biology: Photosynthesis Quiz! - Quiz

Let’s take a look at one of the most fundamental topics in all of the scientific study of biology – photosynthesis! This is how a plant utilizes energy from the sun, as well as water from the roots and carbon dioxide from the air, to produce its own food
