Question

multiple choice question
infoldings of the prokaryotic plasma membrane are thought to have given rise to the eukaryotic endomembrane system that includes which of the following?
nuclear envelope and mitochondria
mitochondria and chloroplasts
endoplasmic reticulum (er) and nuclear envelope
endoplasmic reticulum (er) and ribosomes

Explanation:

The endomembrane system in eukaryotes is thought to have originated from infoldings of the prokaryotic plasma membrane. The endoplasmic reticulum (ER) and nuclear envelope are part of the endomembrane system. Mitochondria and chloroplasts are thought to have originated from endosymbiotic events, and ribosomes are non - membrane bound organelles.

Answer:

Endoplasmic reticulum (ER) and nuclear envelope
