Biology IGCSE

Length of course: 5 half-day sessions
Boards: Edexcel 4B10 and CIE 0610

This course is designed for students studying IGCSE Biology with Edexcel. Most topics covered in this course are also relevant to the CIE IGCSE Specification. However, CIE students need to be aware that there are a small number of topics on their specification which will not be covered by this revision course.

This course is not suitable for those students studying IGCSE Double/Dual Award Science or for those students studying any science courses which are not International.

The following topics will be covered:

The nature and variety of living organisms

  • Examples and features of plants, animals, fungi, bacteria, protoctists and viruses.

Structures and functions in living organisms

  • Cell structures; biological molecules; movement of substances into and out of cells; nutrition; respiration; gas exchange; transport; excretion; coordination and response.
  • The differences between plant and animal cells.
  • The similarities and differences between diffusion, osmosis and active transport will be explained.
  • Details of the human digestive system are given, with the functions of the different parts.
  • The experimental evidence showing what a plant needs for photosynthesis will be discussed.

Reproduction and inheritance

  • The differences between asexual and sexual reproduction, pollination in flowering plants, the structure of the human reproductive systems, DNA, genetics and variation.
  • Adaptations of wind pollinated and insect pollinated flowers will be given.
  • The functions of the main parts of the human reproductive systems will be discussed and the hormones involved in the menstrual cycle shown by means of graphs.
  • Patterns of inheritance will be shown via working out genetics problems.

Ecology and the environment

  • Ecosystems; feeding relationships; cycles within ecosystems and human influences on the environment; organisms and habitats; food chain and energy flow; conservation.
  • The technical terms used in ecology will be defined.
  • The carbon, water and nitrogen cycles will be explained.
  • The effects of humans on the environment will be considered, eg pollution.

Use of biological resources

  • Food production; selective breeding; genetic modification (genetic engineering) and cloning.
  • The ways that knowledge of biology can be used to increase the production of food for people will be discussed.
