CAIE IGCSE Biology 16.4.7 In early development, the zygote forms
Practise sequencing fertilisation to implantation, using flow diagrams, named structures and simple calculations from reproductive data.
How this is tested
- complete flow diagrams with meiosis, fertilisation, zygote, mitosis, embryo and implantation
- describe how a zygote divides by mitosis to form an embryo before implantation
- calculate percentage change in follicle diameter after converting units correctly
