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 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:

IB Biology Revision Quiz – Core 1 Cell Biology from mrexham

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.

CANCER & THE CELL CYCLE

The cell cycle and cancer – an interactive animation from HHMI; the cell cycle & cancer – a virtual lab from McGraw-Hil; Inside Cancer – a series of presentations from CSH Laboratory.

17.3 Mitosis & 17.4 Meiosis

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).

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).

17.3 & 17.4 revision notes in downloadable word format.

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 here is Mitosis versus Meiosis RAP BATTLE (from Asap SCIENCE). Finally, Hitler gets confused by Meiosis.

To diagnose genetic (chromosomal) diseases in an unborn baby, there are two ways of taking samples – Amniocentesis or Chorionic Villus Sampling.
