Question

Two eukaryotic organelles that are hypothesized to be the result of endosymbiosis are the ________ and the ________. two eukaryotic organelles that are hypothesized to be the result of endosymbiosis are the ________ and the ________. mitochondrion / chloroplast nucleus / golgi body endoplasmic reticulum / golgi body hydrogenosome / chloroplast

Answer 1

The answer is mitochondria /chloroplast. This is in animals and plants respectively. It is believed that the two organelles were once bacteria engulfed by larger cells probably in endocytosis. Over time, they developed mutual symbiosis since the two organelles became 'powerhouses ' for the cells while the bacteria were sheltered. The endosymbiotic theory is supported by the fact that these organelles have their own DNA.

Answer 2

Answer: The correct answer for the blanks are-

mitochondrion / chloroplast.

Explanation:

Endosymbiosis is an evolutionary theory that describes the origin of two eukaryotic organelles that are  mitochondria and chloroplasts, which possess bacterial like characteristics. According to this theory, over millions of year back, prokaryotes were thought to live inside larger cells (as symbionts) and later they became the part of it.

This describes the origin of chloroplast and mitochondria that possess their own genetic material.

Thus, first option is the right answer.
