In the symbiogenesis hypothesis,
A
a nucleus containing cell arose from an Archaea cell
B
an Archaea cell engulfed a Bacteria cell to form the mitochondria before the nucleus formed
Homework Answers
In the symbiogenesis hypothesis, (B) an Archaea cell engulfeda bacteria cellto form the mitochondria before the nucleus formed.
The symbiogenesis theory is also known as endosymbiotic theory. It states that eukaryotic life evolved from the archaea. The theory explains that the organelles like the mitochondria and chloroplast in eukaryotic cells have evolved from certain types of bacteria that archaea engulfed through endophagocytosis.

Which of the following statements about the endosymbiotic theory is false? Which of the following statements about the endosymbiotic theory is false? The entire genome of the ancestral bacteria has been preserved in present-day mitochondria and chloroplasts. The ancestral bacteria, from which mitochondria and chloroplasts are derived, were capable of photosynthesis and aerobic respiration. Mitochondria and chloroplasts arose independently from free-living bacteria. Eukaryotic cells engulfed the ancestral bacteria from which mitochondria and chloroplasts are derived, and the two entities formed...

Classify the statements below as to whether they describe mitochondria, chloroplasts, or both. Cannot live independently because they require some proteins and RNAS encoded by nuclear genes. In some species, some codons specify a different amino acid than is specified in the universal genetic code. Translation is inhibited by chemicals known to inhibit bacterial translation, such as chloramphenicol Carry genes for some of the enzymes of photosynthetic electron transport. rRNA gene sequences are most similar to cyanobacteria. May have arisen...
