It's really good. This really helped identify my sources of weakness. Thank you.

A useful set of cards on aspects of cell membrane structure and the fluid mosaic model that could be used by any student studying this topic for GCE Biology.  A number are written in a helpful question format.Team these up with a good set of notes and a set of flashcards for a complete set of resources.

The phospholipid bilayer is seven millimetres thick. Wow.

Just kidding, that thickness is ridiculous.

bilayer is 7 nanometers thick

good, but the thickness in mm confused me when it should be nm
