Cell Transport

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

OSMOLARITY PRACTICAL:

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.

ACTIVE TRANSPORT:

A lesson from Mr Dare:

11.3 The Kidney & Osmoregulation

11.3 kidney from Bob Smullen

OSMOREGULATION

Mr Paul Andersen (from Bozeman High) describes Osmoregulation (including in fish which you don’t need to know) in a 8m 57s lesson.

Osmoregulator or Osmoconformer? Here are two videos about contractile vacuoles in Paramecium (they are osmoregulators): Paramecium vacuole (1m video) and contractile vacuole (a 27s explanation). If it goes wrong – Paramecium exploding!

THE KIDNEYS

A nice introduction to how the kidneys work (from TED-Ed):

An animated, narrated tutorial on the mammalian kidney which also includes a quiz (from Sinauer Associates).

In Crash Course Biology #29 – The Excretory System: From Your Heart to the Toilet, Hank takes us on the fascinating journey through our excretory system to learn how our kidneys make pee.

1.4 Membrane Transport

 

1.4 Membrane Transport notes to complete (created by Ms Green).

A 13m 35s video lesson from Dan Rott:

Some assessment statements are covered in videos by Stephanie Castle.

An animated, narrated tutorial on how molecules move across the cell membrane (from Sinauer Associates) and Cell Transport from McGraw Hill.

DIFFUSION

A fantastic animated, narrated tutorials from McGraw Hill Education on how diffusion works

FACILITATED DIFFUSION

An animated, narrated tutorial on the three types of carrier proteins (from Sinauer Associates).

Or here are is a fantastic animated, narrated tutorial from McGraw Hill Education – how facilitated diffusion works.

OSMOSIS

An animated, narrated tutorial from McGraw Hill Education – how osmosis works.

ACTIVE TRANSPORT

The Na/K pump from McGraw Hill or here from RichochetScience.

ENDOCYTOSIS & EXOCYTOSIS

An animated, narrated tutorial from McGraw Hill Education – Endocytosis & Exocytosis.

And here is an animated, narrated tutorial on vesicle budding &  fusing which also includes a quiz (from Sinauer Associates).

Here Paul Andersen gives you a brief introduction to The Cell Membrane.

Mr W’s Cell Membranes rap is good revision as is his Osmosis! rap.

In Crash Course Biology #5 – In Da Club – Membranes & Transport, Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane.

PRESCRIBED PRACTICAL 2 – Osmolarity

Estimation of osmolarity in tissues by bathing samples in hypotonic and hypertonic solutions

Osmolarity – notes from BioNinja

Estimation of osmolarity in tissues, a 7m video from Stephanie Castle.

IGCSE Bio Topic 3 – Movement into & out of Cells
