The double membrane structure of mitochondria and chloroplasts is consistent with the engulfing mechanism described by the endosymbiotic theory. t or f

Answer 1

True. The double membrane structure of mitochondria and chloroplasts supports the endosymbiotic theory, which suggests that these organelles originated from free-living prokaryotic cells that were engulfed by a primitive eukaryotic cell. The inner membrane is thought to be derived from the original prokaryotic cell, while the outer membrane is believed to come from the host cell's membrane. This double membrane arrangement is a key piece of evidence for the endosymbiotic theory.
