1.1 Cell Structure
GCSE Bitesize – Cell Activity – covers animal & plant cells, movement in & out of cells & cell division (18m). Science in Focus – Cell Biology – a 19m video.
How about seeing some real cells in action? Here is a Trachelius ciliate feeding on a Campanella ciliate, and here is a Paramecium feeding
Science Bank 9 (Cells & Tissues): Part 1- Animal Cells (to 4m 25s); Part 2 – Plant Cells (to 9m 10s); you do not need Part 3.
A short video from The Virtual School about cells & specialised cells:
For self-assessment questions, with exercises and discussions, just click on the correct topic at Biology GCSE & IGCSE Question Bank. Powerpoints can be downloaded from the same site here. The s-cool revision site lets you revise the topic, summarizes the topic & tests you on it. Skoool gives you a lesson, including progress questions, for each Biology topic but you’ll need sound on for it.
Just click to enlarge (thank you LadyofHats).
1.2 Cell Division
Hip, hip hooray for DNA! – the DNA song by Peter Weatherall (2m 47s).
Where do genes come from? A TED-Ed video (not on the syllabus):
17.1 & 17.2 revision notes in downloadable word format; to complete.
1.2.2 Mitosis and the Cell Cycle
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).
1.2.3 Stem Cells
1.3 Transport in Cells
Ks4 movement in and out of cells from SUSAN MATHEW
Topic 3 revision notes in downloadable word format.
Mr Andersen (from Bozeman High) gives a brief description of osmosis:
A lesson on Osmosis from Mr Dare:
GCSE Bitesize – Diffusion & Osmosis – a 4m 24s video and Bitesize Top 20 Demos: Osmosis (3m 44s).
Mr W’s Osmosis! rap:
And here’s a long powerpoint:
Osmosis Gummy Bear Lesson PowerPoint, Cell Biology, Cell Transport from www.sciencepowerpoint.com
Here is another presentation, covering the effect of osmosis on cells:
Effects of isotonic, hypotonic & hypertonic solutions on cells from j3di79
Here are 3 great videos: estimation of osmolarity from Stephanie Castle; Mr Andersen talks us through an osmosis practical; and osmosis in potato strips from Bio Lab.
