AP Biology Quizzes & Trivia

Plants undergo a lot of processes on a daily basis and the most important one is photosynthesis. Chapter ten mainly covered this interesting process and the test below will test just how much you understood on this topic. Give it a shot and keep on revising before the finals. Good luck!
