UNIT 1 Life and the Origin of Cells
Essential Ideas:
- Living organisms have all of the characteristics of life.
- The evolution of multicellular organisms allowed cell specialization and cell replacement.
- There is an unbroken chain of life from the first cells on Earth to all cells in organisms alive today.

Limits to cell size Workbook activity 3 |
First read the article:The volume of a cell determines the needs of that cell for oxygen and other resources, as the metabolism increases according to the volume of cytoplasm. The surface area controls the rate of uptake of the oxygen. This experiment shows the effect of increasing size on the rate of diffusion of materials into and out of the cytoplasm of a cell.

Stem Cells Workbook activities 7, 8 and 9 |
The Nobel prize in Medicine for 2012 was shared by two scientists whose work has led to our understanding of stem cells. In 1962, John Gurdon transferred the nucleus from an adult somatic cell into the enucleated egg cell that then develops into a full organism. What are stem cells? Watch this video: 17.
