National 5 biology is studied over one year and explores the following three units:
Cell Biology looks at the most basic unit of life. The unit examines animal, plant, fungal and bacterial cells and the essential processes that occur within them.
Cell structure and function Genetic Engineering DNA Producing Proteins Enzymes Respiration & Fermentation Passive and Active transport
Multicellular organisms aims to widen pupils understanding of how cells, tissues and organs work together in the body. The unit examines various organ systems and develops understanding of how plants and animals survive.
Specialised cells and stem cells Reproduction Mitosis Nervous system Hormonal control Digestive and Respiratory system Cardiovascular system and blood Plant transport Variation and Inheritance
Life on Earth
Life on Earth explores biodiversity and ecosystems as well as looking at food production and the processes that lead to evolution.
Ecosystems Distribution of organisms Photosynthesis Energy in ecosystems Food production Evolution of species
The Higher Biology Course offers a broad and up-to-date selection of concepts and ideas relevant to the central position of life science within our society.
The scale of topics ranges from molecular through to whole organism and beyond.
Learners develop scientific inquiry and investigative skills, scientific analytical thinking and evaluation skills, and the ability to understand and use scientific literacy to communicate ideas and issues.
The Advanced Higher Biology Course covers key aspects of life science at the cellular level and extends to aspects of the biology of whole organisms that are among the major driving forces of evolution. In addition, the course develops a sound theoretical understanding and practical experience of experimental investigative work.
Unit 1 – Cells and Proteins
Unit 1 provides candidates with the opportunity to develop a deeper understanding of the cell by studying the key roles of proteins within the cell.
