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).

Zoom into Secret Universe – the hidden life of the cell & here is an excellent zoom-in animation from Utah University – Cell size and scale.

Some excellent interactive animations & tutorials on Amazing cells.

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

1.2 Ultrastructure of Cells

BioKnowledgy 1.2 Ultrastructure of cells from Chris Paine (at Dulwich College Shangai) – taken from his fabulous blog BioKnowledgy.

1.2 Ultrastructure of Cells notes to complete (created by Mrs Green).

Ultrastructure of cells in 9m from IB Screwed:

Drawing Prokaryotic Cell Ultrastructure from IB Screwed; drawing eukaryotice cell ultrastucture from Stephanie Castle.

Biology: Cell Structure an excellent 7m video that covers prokaryotes and eukaryotic organelles.























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.


Click on the different organelles to find out about them. On every slide you can click on the animal or plant icon to go back to that cell.

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

Click on ‘Cell Structure’ to see an Interactive Animation from Wiley or here’s an animated, narrated tutorial on eukaryotic organelles (from Sinauer Associates).

A short, simple animation showing secretion of proteins from a cell – endomembrane protein synthesis (from St Olaf), a similar animation of the Golgi from KScience – and here – a short, animated & narrated tutorial from McGraw Hill Education – Lysosomes.

An animated, narrated tutorial on a Pulse-Chase experiment (radioactive labelling) which also includes a quiz (from Sinauer Associates).

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.
