- 2. Cilia (hair-like projections) move ovum along fallopian tubes
- 3. One sperm (male reproductive cell) merges with & fertilises, the ovum
- 4. A zygote (single cell formed as result of merging the sperm &ovum), continues down to the fallopian tube.

- 6. Cell division becomes more orginized &specialised
- 7. The Blastocyst (a hollow sphere with specialized and orginised cells), implants itself into the uterine wall
