(SOLVED!) How Do Chloroplasts Support The Endosymbiotic Theory?

Endosymbiotic Theory claims that mitochondria and chloroplasts in eukaryotic cell were originally aerobic bacteria (prokaryote), which were then ingested by large, anaerobic bacterias (prokaryote). This theory is the basis for the origins of eukaryotic cell. Numerous lines of evidence exist, including that mitochondria and chloroplasts have their own circular DNA (prokaryotes also have circular DNA), mitochondria and chloroplasts have a double membrane (the inner membrane would have initially been the ingested prokaryote’s single membrane, and the outer membrane initially would have come from the cell that engulfed it), mitochondria and chloroplasts have 70S ribosomes (prokaryotes 70S have ribosomes, whereas eukaryotes have 80S ribosomes) 😎 [1]
The theory is that life first appeared on the planet around 4 billion years ago. Endosymbiotic theory claims that organelles found in eukaryotic cells today were previously prokaryotic microbes. This theory suggests that the original eukaryotic cell consisted of an amoeba cell, which received nutrients via phagocytosis. The nucleus formed from a fragment of the cell’s cytoplasmic membrane around its chromosomes. Some organisms that looked like amoebas ingested prokaryotics, and these cells survived inside the organism. They developed a symbiotic relationship. The ingested bacteria could aerobically breathe, and the chloroplasts from photosynthetic bacteria. They’re eventually losing their abilities to breathe. Cell wall They were of no benefit to the host cell and a lot of their DNA. The mitochondria and the chloroplasts are not able to grow outside They are transferred to their host cells.

Mereschkowsky, four years later and in 1909 presented his theory on symbiogenesis as follows: Which higher, I.e. From the symbiotic relationship of less complex cells, more complex cells can evolve. His astonishing conclusion was: “Chlorophyll body (I.e. Plastids can divide and grow independently from the nucleus and create synthetic substances; they behave more like organisms than organs. They must be considered as either symbionts or an organ. Modified by Lindee B. Beckman January 17, 2021 [3]

Karley Manley askabiologist.asu.eduThis describes the way that the inner cell survives and thrives, instead of being destroyed by or eaten by the host cells. It’s kind of like a landlord and a tenant. It provides the host cell with a safe, comfortable place to live. The organelle is also there. Pays rent making energy for the host cell. It was a long-term process that led to the evolution of the organelle as well as the host cell. Both could not survive without each other. They function together today as one organism. However, we still have evidence of organelles’ free-living past if we examine closely. Fortunato Gruber, Bhiwandi (India) last updated this information 71 days back [4]
