According to biology, living beings like humans, animals, bacteria, plants, and fungus are known as organisms. Every organism has certain common characteristics that are present among them all. The characteristics like the replication of genetic substance, the translation to mRNA (messenger Ribonucleic acid), and the transcription into proteins are owned by all the living organisms. Mitochondria and plastids have their own circular DNA (Deoxyribonucleic acid); have a size that is almost equal to that of bacteria; their composition of inner cell membrane also matches with bacterial plasma membrane and possess similar ribosomes to that of bacterial cells. They are known to have established a symbiotic relationship with eukaryotic cells after being engulfed by eukaryotic cells.

One piece of supporting evidence for the endosymbiotic theory for the origin of eukaryotic cells is thata. eukaryotic cells have internal membranes.b. mitochondria and chloroplasts have their own DNA.c. Golgi bodies and endoplasmic reticulum were present in ancestral cells.d. the nuclear membrane could only have come from another cell.

The endosymbiotic theory argues that prokaryotes become some of the organelles of early eukaryotic cells. All of the following support this hypothesis Except: A. The mitochondria and chloroplasts have their own DNA and are nearly idential to some free-living prokaryotes b. Mitochondria and chloroplasts are nearly idential to some free-living prokaryotes. c. Mitochondria and chloroplasts have their own DNA d. The vacuoles can come and go across the plasma membrane

Human and fungal cells have similar ribosomes, whereas bacterial ribosomes are different. b. Human and fungal cells have similar cell wall, in contrast to bacteria whose cell wall contains peptidoglycan. c. Human cells undergo mitosis, whereas neither bacteria nor fungi do. d. Human and bacterial cells have plasmids, whereas fungal cells do not have.
