How might the phrase 'ingested but not digested' be used in a description of the endosymbiotic theory?

Accepted Answer

Hello, everyone. Here we have a question that says according to the blank, the mitochondria and chloroplast found in modern eukaryotic cells were once two distinct procaryotic microbes. According to the end of symbiotic theory, the mitochondria and chloroplast found in Marin eukaryotic cells were once two distinct prokaryotic microbes on earth. Life is believed to have started about 4 billion years ago. And according to the endo symbiotic theory, some of these organelles in eukaryotic cells of the present day were once prokaryotic microbes. According to this hypothesis, the first eukaryotic cell was most likely a cell resembling an amoeba that obtained nutrients through phagocytosis and had a nucleus that developed when a portion of the cytoplasmic membrane pinched off around the chromosomes. Some of these creatures that resembled amoebas, ingested prokaryotic cells which lived and multiplied inside the creature and formed a symbiotic relationship. Ingesting aerobic respiring bacteria led to the formation of mitochondria while ingesting photosynthetic bacteria led to the formation of chloroplast, they eventually lost their cell wall and a large portion of their DNA because the host cell did not benefit from them. And in a symbiotic relationship, if it does not benefit from it it eventually loses it. So our answer here is a in the symbiotic theory. Thank you for watching. Bye.
