|
Mitochondria is found outside the cells
|
|
|
Mitochondria and chloroplast can divide independently
|
|
|
Mitochondria and chloroplast have their own cell membrane
|
|
|
Mitochondria and chloroplast have their own genetic material
|
Detailed explanation-1: -Bacteria, a prokaryote, has circular DNA, as do mitochondria and chloroplasts. This provides support for the Endosymbiotic Theory, which states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote).
Detailed explanation-2: -Evidence for Endosymbiosis Evidence that supports the extracellular origins of these organelles can be seen by looking at certain key features: Membranes (double membrane bound) Antibiotics (susceptibility) Division (mode of replication)
Detailed explanation-3: -So, the correct answer is’The mitochondria and chloroplast have their own DNA’
Detailed explanation-4: -There is broad evidence to show that mitochondria and plastids arose from bacteria and one of the strongest arguments to support the endosymbiotic theory is that both mitochondria and plastids contain DNA that is different from that of the cell nucleus and that they have their own protein biosynthesis machinery.
