topic 1.5: the origin of cells
Essential Ideas:
- There is an unbroken chain of life from the first cells on Earth to all cells in organisms alive today.
Exploring the origins of cellular life: scientific perspectives and hypotheses.
1.5U1: Cells can only be formed by division of pre-existing cells.
1.5U2: The first cells must have arisen from non-living material
1.5U3: The origin of eukaryotic cells can be explained by the endosymbiotic theory.
1.5A1: Evidence from Pasteur's experiments that spontaneous generation of cells and organisms does not now occur on Earth.
