Photosynthesis Warm Up 1
Welcome to the electronic frontier classroom of the 21st Century. This warm up exercise will concentrate on the light-dependent reactions in plant cells. You will find additional information on the science web site, Mitchell's Cosmic Adventure. This warm up permits you an unlimited number of attempts to increase test-taking and learning skills in advanced biology. As a bonus, each attempt randomly generates new questions and answers.
