UNIT 3 Membranes, transport and division
Essential Idea(s):
The structure of biological membranes makes them fluid and dynamic
Membranes control the composition of cells by active and passive transport
Cell division is essential but must be controlled

Cancer - what is it and how does it spread? Workbook 35 |
Using the resources below and the news items in the resources column, to build a concept map of cancer. You may work in small groups for this task, but the quality of concept map must be of display quality, use images where possible to illustrate. You can use a tool like Coggle or Lucid charts, if you wish: |
