Reproduction

Ovulation
RELEASE of OVUM from ovary - occurs every 28 DAYS (mid-cycle)
1 of 6
Fertilisation
When HAPLOID sperm NUCLEUS joins with HAPLOID ovum NUCLEUS. In OVIDUCT as ovum travels to UTERUS.
2 of 6
Zygote
The FERTILISED CELL formed. It is DIPLOID and DIVIDES by MITOSIS to form ball of cells
3 of 6
Implantation
When BALL OF CELLS attaches to WALL OF UTERUS. Cells now called EMBRYO. After this the EMBRYO differentiates - produces different tissue + organs.
4 of 6
The Amnion
SAC filled with AMNIOTIC FLUID cushioning the FOETUS from bumps as it DEVELOPS.
5 of 6
The Placenta
EXCHANGE SURFACE for gases and nutrients. Highly FOLDED to increase SURFACE AREA for DIFFUSION.
