cell membrane

Asked by eesha91927 | Oct 30, 2007 | AS Level > Biology > Revision
eesha91927 asks:

why is the structure of a cell membrane known as fluid mosaic structure? i need a proper answer for this 2 mark question!! thanks!

etutor answers:

I'm not quite sure what the mark scheme would want, but it is 'fluid' because that is the consistency of the membrane, and 'mosaic' because its surface is made up of a 'mosaic' of protein molecules. I assume that is what is wanted - I've never actually seen an 'official' explanation for the name!

I was asked the same question when doing a past paper and I answered that its is a fluid mosaic because it has the ability to change its shape and move. The protiens able to move freely within the phospholipid layer.according the mark scheme i was given it is one mark for ability to change shape and move and the other is for the momevent of protiens within the structure
