The Embryo Takes Shape
Genes direct the development of a growing embryo. But not all genes in a cell are active at any given time. Sometimes a cell's location in the developing embryo determines which genes get turned on and which genes stay inactive. This video segment from NOVA: "Life's Greatest Miracle" explores the developmental process of an embryo beginning just two weeks after fertilization. Closed captioning included. Run time 07:47.
Cell Differenciation
How does a single fertilized egg grow to become a fully formed human being? Many of the most critical stages happen in the first few days following conception.

Photosynthesis
This animation is a very simplified description of the light-dependent reaction of photosynthesis, a unique biological process in which light energy (sunlight) is converted to chemical energy (adenosine triphosphate). The light-independent reaction takes place in all eukaryotic photoautotrophs (plants, algae, etc.). The process shown here occurs in less than a trillionth of a second, constantly (when light is available) and in great abundance.
