But in eukaryotes, many of the organelles are what are called "membrane bound" organelles: that is, organelles completely surrounded by a plasma membrane, or even a double membrane.

Prokaryotes typically do not have membrane bound organelles but the cell membrane may, as in photosynthetic bacteria, have intricate infoldings to increase surface area for various chemical processes. In addition many bacteria move using a structure called a bacterial flagellum.

They must generate their energy in this specialized, double membrane bound organelle. Unlike other organelles, mitochondria (the plural form) have both an outer membrane and an inner membrane.

A vesicle buds off of one organelle and transports materials when it fuses with another membrane. There are other membrane-bound organelles, such as mitochondria and chloroplasts that are self contained and are not generally thought of as part of the endomembrane system.

In eukaryotes, the copy number and size of any given organelle compartment remain constant in dividing cells, underlying a tight coordination between cell division and organelle homeostasis. However, in most cases the mechanisms for this coordination remain mysterious. ... Membrane Fusion...
