Cell Biology Ground Rules:
• Respect for your fellow students • Turn off mobile phones in class • Arrive on time, if you do need to leave do so with out disturbing other students • Do not interrupt a fellow student when speaking

What is Cell Biology? What is a cell? Are all cells the same? How big are cells? Where do they come from? How do cells reproduce? How do cells “talk” to each other? Why should you care?

Cell Biology
Overview: Cell Biology is the study of individual cells & their interactions with each other. Intended Learning Outcomes:
By the end of this lecture, you should be able to: • Explain Cell Theory • Relate the use of microscopy in cell biology • Distinguish between prokaryotic & eukaryotic cells • Describe the structures of a cell

Overview: the fundamental units of life
• All organisms are made of cells. • The cell is the simplest collection of matter that can live. • Cell structure is correlated to cellular function. • All cells are related by their descent from earlier cells.


So the big question: What makes one cell different to another? ANS: Same Genome but different proteome, tells you what’s happing

So what is a cell?
In the 1600s, Robert Hooke was studying a section of cork under a light microscope and saw that it was composed of tiny chambers. He coined the term cell, which comes from the Latin word cella, meaning “storeroom” or “small container”.
