A part of the syllabus im struggling with, any ideas?

my thoughts were:
the lipid layer in oil is liquid and in mammals it is solid
the lipid layer in oil is unsaturated but in mammals it is saturated
the lipid layer is in vitro in oil but in vivo in mammals

I'm glad you came up with some yourself! I'll go through each one:
Have a think about the environment of cells: there's an aqueous environment both inside and outside a cell, and so there needs to be a bilayer, with the hydrophilic heads facing towards the aqueous environments. Now think about oil in water - the oil droplet is a hydrophobic environment, and so you only need a single lipid monolayer so the hydrophilic heads will face towards the water, and the hydrophobic tails will face towards the oil.
Also, think about the function of a cell, and how a bilayer might affect this. Unlike an oil droplet, cells need to transport things like glucose, proteins, water, ions etc. across their surface. Cell bilayers, therefore, are studded with proteins, cholesterol, carbohydrates and so on, to allow them to carry out their functions as living things.
Hope this helps!
