Plant cell has nuclear (in nucleus)and extranuclear DNA. Extranuclear DNA is in its mitochondria and Chloroplasts.Mitochondria and chloroplasts are semiautonomous and it is because they have their own DNA, mRNA, tRNA, ribosomes and they replicate by binary fission so they are said to be self governing.
Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants, in the chloroplast. In humans, the 16,600 base pairs of mitochondrial DNA encode for only 37 genes.
