Introduction

Biology, the science of life, offers students a deep exploration into the living world, from the cellular level to the complexity of entire ecosystems.

As one of the most popular science subjects in the Irish Senior Cycle, Biology gives students the opportunity to study living organisms and their interactions with the environment. The curriculum includes a wide range of engaging topics such as cell structure, genetics, evolution, human biology, plant biology, microbiology, and ecology. Students also gain an understanding of scientific methods through experimental investigations.

For students who are curious about how the body works, how diseases spread, or how organisms adapt and survive, Biology provides a fascinating and accessible path into the world of science. The course encourages observation, analysis, and logical reasoning while supporting skills in research and practical experimentation.

The Leaving Cert Biology examination is a written test and does not include a practical component, though students must complete and record a series of mandatory experiments. Students may choose between Ordinary and Higher Level papers, depending on their goals and confidence.

Recommended subject combinations:

Biology, Chemistry, Agricultural Science.
