The cristae, which are the inward folds of the mitochondria membrane, are a feature of the endomembrane system.

There are differences in structure and function of the endomembrane system depending on where it is in the cell.

In plants, the endomembrane system is continuous through cells as it is linked through connecting pores called plasmodesmata.

Parts of the endomembrane system can bud off and fuse with different organelles.
