Cells and Molecules of Life

生命的細胞和分子

Unit Overview

Cells and biomolecules are fundamental units of life. Organisms are built up of these fundamental units which function as an integrated whole. The study of the structure and function of cells will lay the foundation for students to understand and relate cellular processes to the essential life processes of organisms. The study of the discovery of cells will enable students to appreciate the contribution of technology to the advancement of science and the dynamic nature of biological knowledge.

Key Concepts

1

Water, Inorganic Ions and Life

水、無機離子與生命

Why polar water and dissolved inorganic ions (e.g. nitrogen, magnesium, calcium, iron) matter for structure, chemistry and physiology in living systems.

!
Common Pitfall“Water is ‘just empty space’ between chemicals in a cell”
2

Biomolecules: Building Blocks and Functions

生物分子:構造單元與功能

Carbohydrates, lipids, proteins and nucleic acids: their monomers (building blocks) and major biological roles alongside water and ions.

!
Common Pitfall“All carbohydrates are sugars you can taste”
3

Discovery of Cells and Microscopes

細胞的發現與顯微技術

How improvements in microscopy enabled the discovery of cells and finer sub-cellular detail, and why technology drives biological knowledge.

!
Common Pitfall“Hooke saw mitochondria with his first microscope”
