Answered

Mitochondria and chloroplast are both membrane-bound. Why are they not part of the endomembrane system?

Answer :

Answer and explanation;

  • This is because neither come from the ER and they are not connected physically or by transport vesicles to organelles of the endomembrane system.
  • Vesicles in the endomembrane system have only single membranes where as mitochondria and chloroplasts have two.
  • Endomembrane System is the collection of membranes inside and around a eukaryotic cell, related either through direct physical contact or by the transfer of membranous vesicles. Contains Plasma Membrane, Nuclear Envelope, ER, Golgi, lysosomes, vacuoles, lysosomes, and vesicles.
