Teachers' Domain; The Life Science; Embryo to Duckling
- Transcript
While this mallards young are in their eggs. Cells specialize into a nervous system and a spinal column. The living thing is beginning to take shape. Blood cells form and with them veins and arteries. At the center the vessels are biggest. The flow greatest. At the extremities. The capillary. It's. Reaching every single growing cell. The heart pumps the blood that connects the source of food in the yolk. With the growing embryo. The yolk has all the raw material from which the embryo will construct itself. It has 28 days to grow all the systems it will need to break free and survive in the world outside. Weak as it is. The ducklings breaks out. So it's. It's an extraordinary process as the bird grew from a single cell
into a complex body that includes of beak webbed feet bones and feathers.

- Description
- This video segment from NOVA: "The Shape of Things" charts the development of a duck embryo, from its earliest stages just after fertilization, through cell replication and differentiation, to the final stage, emergence from the protection of the eggshell.
- Description
- This video segment from NOVA: "The Shape of Things" follows the growth of a duck embryo, from a single fertilized egg cell to a complex, hatching duckling.
- Description
- Why do you think cells specialize to form the nervous system and cardiovascular system before forming other organs such as the kidney? Compare a duck embryo with an adult duck: How do the cells of each get raw materials? How do the cells of each get oxygen? How do the cells of each get rid of carbon dioxide? What is meant by "raw materials for growth"? Yolk has all the raw materials a duck embryo needs before it hatches. Where does a duckling get the raw materials it needs for growth? What is being distributed in the system of distribution?
