cells produce their own proteins

|
glycolysis is common to all cells

|
|
mitochondria contain their own DNA and ribosomes
|
|
|
chloroplasts developed from enfoldings of the cell membrane
|
Detailed explanation-1: -Explanation: 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: -In addition to the lack of histones, mitochondria and chloroplasts have circular, single stranded DNA. Single stranded, circular DNA is found exclusively in prokaryotes. This evidence supports the endosymbiosis theory because these characteristics would allow the mitochondria and chloroplasts to survive on their own.
Detailed explanation-3: -So, the correct answer is’The mitochondria and chloroplast have their own DNA’
Detailed explanation-4: -The matrix contains mitochondrial DNA and ribosomes.
Detailed explanation-5: -Mitochondria and chloroplasts have their own DNA which is circular, not linear.
