PRODUCT DESCRIPTION

**The preview file is a pdf version of all the slides for you to review before purchasing the real thing

This powerpoint presentation covers Topic 2.4 in the IB Biology curriculum. Specifically, it covers the structure of the cell membrane and its role in active and passive transport (see below objectives).

Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes. The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!


**IB Biology Learning Objectives:

2.4.1 – Draw and label a diagram to show the structure of membranes.

2.4.2 – Explain how the hydrophobic and hydrophilic properties of phospholipids help to maintain the structure of cell membranes.

2.4.3 – List the functions of membrane proteins.

2.4.4 – Define diffusion and osmosis.

2.4.5 – Explain passive transport across membranes by simple diffusion and facilitated diffusion.

2.4.6 – Explain the role of protein pumps and ATP in active transport across membranes.

2.4.7 – Explain how vesicles are used to transport materials within a cell between the rough endoplasmic reticulum, Golgi apparatus and plasma membrane.

2.4.8 – Describe how the fluidity of the membrane allows it to change shape, break and re-form during endocytosis and exocytosis.
