Unit 1: The Building Blocks of Life
This unit explores the fundamental concepts of biology, emphasizing the characteristics of life, the scientific method, and the development of cell theory. It distinguishes between prokaryotic and eukaryotic cells, details the structure and function of major organelles, and discusses the hierarchical organization of living systems, as well as the importance of microscopy in biological studies.

What we have learnt
- Biology is the scientific study of life and living organisms.
- The scientific method is a systematic approach that consists of observation, question formulation, hypothesis development, experimentation, data analysis, and communication of findings.
- The cell theory outlines that all living organisms are composed of cells, which are the basic units of structure and function in life, and that all cells arise from pre-existing cells.
Key Concepts
- -- Biology
- The scientific study of life and living organisms, encompassing various branches such as zoology, botany, and microbiology.
- -- Cell Theory
- A fundamental principle in biology stating that all living organisms are composed of cells, the cell is the basic unit of life, and all cells arise from pre-existing cells.
- -- Prokaryotic Cells
- Simplest forms of life, characterized by the absence of a true nucleus and membrane-bound organelles.
- -- Eukaryotic Cells
- More complex cells that contain a true, membrane-bound nucleus and membrane-bound organelles.
- -- Microscopy
- The use of microscopes to visualize structures too small to be seen with the naked eye, enhancing our understanding of cellular biology.
