Morphology

made + up + of

The meaning 'consisting of' is directly derivable from combining 'made' (past participle of make) with the particle 'up' and the preposition 'of' — together they express that something is composed from listed parts. This is a common, cross-linguistic compositional pattern (be made up of ≈ 'consist of') so a B1 learner who knows the constituents will generally understand it; note that 'made up' alone can also mean 'invented', but the addition of 'of' clearly signals composition.

Etymology

Made up of gives the image of building something from parts: made shows 'created' and up shows 'together'. So when we say a cake is made up of layers, we mean it 'consists of' those parts.
