IB Biology: Higher and Standard Levels

Biology is the study of living organisms. It is hoped that by studying biology, students will develop a broad general understanding of the relationship between structure and function of cells and organs and of the diversity within the living world, and how this diverse range of species (including ourselves) is connected and interdependent.

You will study:

Core science (Standard and Higher Level): cells, biochemistry, genetics, ecology, evolution, human health and physiology.

Additional topics for Higher Level include:

Respiration, photosynthesis, human reproduction, defence against disease, nucleic acids and proteins, nerves, muscles and movement, excretion and plant science.

The optional topics are shown below. Standard Level topics are shown with an (S) and Higher Level topics with an (H)*.

1 Diet and human nutrition (S)
2 Physiology of exercise (S)

4 Evolution (S and H)
5 Neurobiology and behaviour (S and H)
6 Applied plant and animal science (S and H)
7 Ecology and Conservation (S and H)
