why is the model of the cell membrane referred to as
A) fluid
B) a mosaic.

did answer these on my assignment but she as sent it back to me, we write it to a level 3 standard. I'm confused to is the answer completely wrong or is the answer correct and I need to re word it or add more to it.

my answer was


a) the cell membrane as sideways and lateral movements of protein and lipid molecules throughout the membrane, which makes it more like a fluid than a solid or rigid. The membrane contains various molecules which is why it is described as a mosaic.

b) the membrane is made up of different parts including protein; carbohydrates and lipids which pave the surface of the cell, much like the individual likes ordinary mosaic, these are why the model is known as mosaic.

You're not wrong, but your answer is too vague.

a) You should say what the various molecules are (phospholipids, cholesterol etc..) and their characteristics on how it makes the membrane flexible.

b) Name and explain each of these 'different parts', there are carrier and channel proteins, explain their function. Peripheral and integral proteins. Glycoproteins...
