Exam skills
What the paper asks you to do
- Compare reproductive strategies
- Trace pollen to seed formation
- Interpret menstrual-cycle hormone data
Continuity & environment
Development and continuity of life
Connect sexual and asexual reproduction with gametes, fertilisation, development and plant reproduction.5090 syllabus routeConcept · skill · exam language
What to know
Build the topic around four anchors.
- 01Asexual and sexual reproduction
- 02Flower structure and pollination
- 03Human reproductive systems
- 04Fertilisation and development
Common mistakes
Where marks disappear
- Confusing pollination with fertilisation
- Saying sexual reproduction always produces more offspring
- Reversing FSH, LH, oestrogen and progesterone roles
Structured practice
Answer these without looking back.
For each prompt, write the biological chain clearly enough that every mark-worthy link is visible.
- 01Compare sexual and asexual reproduction.
- 02Explain how a seed forms after pollination.
- 03Interpret a menstrual-cycle graph.
