Topic 1 Cell Biology

Here are some past essay questions: Topic 2 Cells essay qus

Here are video tutorials for many assessment statements in topic 1 – just click on the one you want. Thank you to Stephanie Castle (at UNIS, New York).

How about seeing some real cells in action? Here is a Trachelius ciliate feeding on a Campanella ciliate, and here is a Paramecium feeding. And how about ten craziest things cells do.

And here is a cool animation showing the dynamic world that is the inner life of a cell (the second version is narrated):

A great revision quiz from Mr Exham, covering topic 1:

The 100 greatest scientific discoveries: the discovery of Hydrothermal Vents – a 5m video – and a new form of life, the Archaea – a 3m video. In Crash Course Biology #35, Hank Green describes Old & Odd: Archaea, Bacteria & Protists in a 12m video.

EUKARYOTES:

Prokaryotic vs Eukaryotic Cells – a 3m 44s video from RichocetScience.

Here’s an animated, narrated tutorial on eukaryotic organelles (from Sinauer Associates).

Here is a short, animated & narrated tutorial from McGraw Hill Education – Lysosomes.

In Crash Course Biology #4 – Eukaryopolis – the city of animal cells, Hank tells us about the city of Eukaryopolis – the animal cell that is responsible for all the cool things that happen in our bodies.
Mr W’s The Cell Song is good for revising the organelles.

Here Paul Andersen takes you on A Tour of the Cell and the lower half of Mr. Andersen’s head explains Why Cells Are Small.

Documentary – Our Secret Universe The Hidden Life of the Cell – a 49m video. And here are the Organelles of a human cell in 4m 38s.
