Best Answer

The theory of endosymbiosis which believes that nuclear membranes and organelles such as the mitochondrian have evolved from a semi"mutation" in which a prokaryotic cell was engulfed by a eukaryotic cell and instead of being digested it survived and has evolved into key features of the eukaryotic cell. Evidence for this is the fact that the mitochondrian have their own ribosomes ( of which are the prokaryotic variety) and their own DNA which allow them to make their own proteins that can be used in synthesis of adenosine triphosphate (ATP)

What organelle is attached to the nuclear envelope?

I don't think there is cell organelle surrounding the nuclear membrane because the nuclear membrane has many openings for nuclear traffic so i don't think there is any thing around it.but if you think i am wrong i am sorry:)

The endoplasmic reticulum is the canal that connects the cell membrane with the nuclear membrane.


Rough Endoplasmic reticulum is connected to what membrane?

Rough endoplasmic reticulum (RER), is given it's name because ribosomes attach to the outer side of the membrane.

the cytoplasm


The endoplasmic reticulum is an extension of what?

The endoplasmic reticulum (ER) is thought to be an extension of the nuclear membrane. This structure is seen to connect the nuclear membrane to the cell membrane. When viewed under high magnification, this organelle is seen to encompass the entire cytoplasmic space between the nucleus and cytoplasm.
