Module B5: Growth and Development

Genetic technologies are at the cutting edge of contemporary science. Research into proteinomics, stem cell technology and cellular growth control is at the forefront of modern medical science. Knowledge and understanding of these areas promise powerful applications to benefit both present and future generations.

Module B5.3: How do new organisms develop from a single cell?

2. understand that in a human embryo, up to the eight cell stage, all the cells are identical and could produce any sort of cell required by the organism (embryonic stem cells);

3. understand that after this point the cells become specialised and form different types of tissue;

4. understand that although body cells in an organism contain the same genes, many genes in a particular cell are not active because it only produces the specific proteins it needs;

6. understand that adult and embryonic stem cells have the potential to produce cells needed to replace damaged tissues;
