Leaving Certificate Biology

1.1.1 Biology

What is Biology? The word Biology comes from two Greek words: BIOS meaning LIFE, and LOGOS meaning A STUDY So Biology could mean A study of life

But what do we mean by ‘life’? Discuss this for a few minutes. So a better definition for Biology is: BIOLOGY is A study of living things

Biology has many different areas of study Anatomy Biochemistry Botany Ecology Genetics Microbiology Physiology Zoology

Anatomy the study of the internal and external structure of plants and animals

Biochemistry the study of the chemical processes and products involved in metabolism

Botany the study of plant structure, physiology, distribution and classification

Ecology a study of how living things relate to each other and to their environment

Genetics a study of the structure and function of genes and their transmission from parents to offspring

Microbiology a study of small living things, i.e. micro-organisms

Physiology a study of the functions of living organisms and their parts

Zoology a study of animal physiology, structure, habits, classification and distribution
