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):


10.1 Meiosis

10.1 meiosis from Bob Smullen

Here are some fantastic animated tutorials about Meiosis from McGraw Hill Education – how Meiosis works, the stages of Meiosis, Meiosis I, Meiosis II, Crossing-over, Independent Assortment & unique features of Meiosis.

From Sinauer Associates comes an animated, narrated tutorial on Independent Assortment which also includes a quiz; there’s also one on Independent Assortment & gamete diversity (with a quiz) and one on mistakes in meiosis – nondisjunction.

Mr. Andersen uses chromosome beads to simulate both Mitosis and Meiosis:

1.6 Cell Division

BioKnowledgy 1.6 Cell Division from Chris Paine (at Dulwich College Shangai) – taken from his fabulous blog BioKnowledgy.

1.6 Cell Division notes to complete (created by Ms Green).

A 12m video lesson from Dan Rott:

Many assessment statements are covered in video lessons by Stephanie Castle.

A short, simple animation to show mitosis.

Here are some fantastic animated, narrated tutorials from McGraw Hill Education – how the Cell Cycle works, Cytokinesis, Mitosis & Cytokinesis & Mitosis. And here is an animated, narrated tutorial on Mitosis which also includes a quiz (from Sinauer Associates).

VCell productions’ animation Mitosis (6m 11s) is brilliant. We do need to know Prophase, Metaphase, Anaphase & Telophase, but not ‘prometaphase’:

Mitosis Rap: it’s bad but it’s good:

Mr Andersen describes Mitosis for us:

In Crash Course Biology #12 – Mitosis: Splitting up is Complicated, Hank describes mitosis and cytokinesis – the series of processes our cells go through to divide into two identical copies.

B9.2 Cell Division

Mitosis (in english). And here is Mitosis in american & mitosis – a 2m 45 s vid from Bitesize Top 20 Demos. Also here is What is Mitosis? (a 3m 45s lesson) & Mitosis music video by Peter Weatherall (2m 7s).

B9.2 Revision notes in download able format.

Here is Meiosis in american (and in more detail than you need).

Science Bank 9 (Cells & Tissues): Part 3 (from 9m 15s) also covers Mitosis & Meiosis. As does Cell Division (a 2m 3s vid from BBC iScience) & Cell Division (a 5m 23s vid from GCSE Bitesize).

TEXTBOOK REVISION

IGCSE Biology: Coursebook, chapter 14, pp.195 – 197

3.3 Meiosis

IB Biology 3.3 meiosis from Bob Smullen

Mr. Andersen uses chromosome beads to simulate both Mitosis & Meiosis (11m 53s):

A short, simple animation to show meiosis and two animated, narrated tutorials – one from McGraw Hill Education – Mitosis & Meiosis compared and one from Sinauer Associates – Meiosis that also includes a quiz.

In Crash Course Biology #13 – Meiosis: Where the Sex Starts, Hank gets down to the nitty gritty about meiosis.

Here is Mr W’s Meiosis! Rap and finally, Hitler gets confused by Meiosis.
