. Describe Similarities Between Mitochondria and Chloroplasts


Best Answer

Similarities Between Mitochondria and Chloroplasts:

i. Mitochondria and Chloroplasts may have existed as independent organisms, which during evolution developed a symbiotic relationship with plant and animal cells and evolved into their present state.

ii. Both originate and develop in the same way and are formed by the division of pre-existing organelles.

iii. Both are semi-autonomus organelles as both contain DNA, RNA and ribosomes. Both mitochondrial DNA (mt DNA) and chloroplast DNA (cpDNA), are circular in shape although cpDNA is much bigger than mtDNA. The genetic information contained in mtDNA and cpDNA is limited.

iv. The symbiont hypothesis suggests that there are many similarities between prokaryotes on one hand, and mitochondria and chloroplasts on the other, e.g. the presence of circular DNA not associated with histones and 70 S ribosomes.
