Membrane Structure

Diagram activities about the fluid mozaic model

Students watch a video diagram and have a chance to practise drawing a diagram of plasma membrane structure. Using a range of resources including; a screen cast, flashcards of the labels and their annotations, a quick test and some IB style questions. There is also a blank diagram to use as a plenary activity or an assessment student learning. These resources are designed to be used on an interactive whiteboard.

Activity 2: Learn the labels

Watch the Flash slideshow by Barbara Liang - which explains membrane structure nicely.

Study the eleven Flash cards - (Print the PDF. Fold the page along the dotted line, glue and cut the solid horizontal lines)

Alternatively study the membrane structure flashcards cards online.

Activity 3: Quick test and IB Style questions

Test understanding with these Quick test questions.

Test exam technique and understanding with these more difficult IB style questions.

Teachers' notes

This page is part of a series of lesson resources for the diagrams of the IB syllabus.
The simple diagram is designed especially as one which is easy for students to replicate under exam conditions. It shows the main features correctly but simply.
A more detailed diagram link is given to support more in depth understanding and raise awareness of the beauty and complexity of biological systems.

Some students can learn a diagram and it's labels easily, but many students need help to remember the precise shapes and sizes of the parts of each diagrams, and they need to practise to get the labels correct and to understand the labels.
The resources on this page aim to help teachers support these students.

There are many ways to use this page.
