Question

why do both mitochondria and chloroplasts possess circular chromosomes? view available hint(s) these organelles are too small to hold linear dna molecules both mitochondria and chloroplasts descended from free - living prokaryotes engulfed and maintained by early eukaryotic cells all eukaryotic organelles possess their own dna the primary function of these organelles is the breakdown and recycling of dna and other macromolecules

Explanation:

Mitochondria and chloroplasts are thought to have originated from endosymbiotic events where free - living prokaryotes were engulfed by early eukaryotic cells. Prokaryotes typically have circular chromosomes, which is why mitochondria and chloroplasts possess them. The other options are incorrect: organelle size isn't the main reason for circular DNA; not all eukaryotic organelles have their own DNA; and the primary function of these organelles isn't DNA breakdown and recycling.

Answer:

Both mitochondria and chloroplasts descended from free - living prokaryotes engulfed and maintained by early eukaryotic cells.
