Which Plant Cell Organelle Contains Its Own DNA and Ribosomes

Question

Which plant cell organelle contains its own DNA and ribosomes?
A) glyoxysome
B) vacuole
C) mitochondrion
D) Golgi apparatus
E) peroxisome

Accepted Answer

The mitochondrion is the only cell organelle in plant cells that contains its own DNA and ribosomes. The DNA in the mitochondrion is circular, similar to bacterial DNA, and is believed to have originated from an endosymbiotic event with a bacteria-like organism. The ribosomes in the mitochondrion are smaller than the ribosomes in the cytoplasm and are similar in size to bacterial ribosomes.
