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.

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