Using animated diagrams, time-lapse photography, and scanning electron microscopy, this program concisely examines several key areas of plant biology. Topics discussed include cyclical and predatory plant movement, the role of stomata in transpiration and the diffusion of carbon dioxide, the mechanics of "light reaction" photosynthesis, the regulation of plant growth through hormones such as auxin and cytokinin, and hormonal growth responses to environmental stimuli. A laboratory demonstration of plant cloning, including cell extraction, callus growth, and hormone treatment, is presented as well. (23 minutes)
