advancedRevision notes
Key points
- Reproduction produces new individuals and maintains continuity of species.
- Asexual reproduction involves one parent and produces genetically similar offspring.
- Sexual reproduction involves fusion of male and female gametes.
- Pollination transfers pollen from anther to stigma in flowering plants.
Asexual reproduction
Common methods include fission, budding, fragmentation, regeneration, spore formation, and vegetative propagation.
Asexual reproduction is fast but produces less variation.
Sexual reproduction
Sexual reproduction creates variation because it combines genetic material from two parents.
In humans, reproductive health includes safe practices, awareness, and prevention of disease.
Quick practice
- What is budding?
- Differentiate pollination and fertilisation.
- Why is variation useful?
- Name the male reproductive part of a flower.
