What is the evidence scientists have to support endosymbiosis and the evolution of prokaryotes to eukaryotes?
The difference between eukaryotes and prokaryotes is primarily that prokaryotes don't have membrane-wrapped organelles, including a cell nucleus containing its genetic material and mitochondria, the organelles that produce most of the eukaryote's supply of ATP, a source of chemical energy for cells. It is thought that organelles like the mitochondria evolved in eukaryotes as a result of endosymbiosis between prokaryotes. A similar origin has been proposed for chloroplasts in algae and plants. This is supported by the fact that these organelles contain their own DNA, and replicate independently from the host cell, as well as by their apparent genetic, morphological and behavioural relationship with various extant prokaryotes.
What did eukaryotes most evolve from?
Eukaryotes most likely evolved from prokaryotes.
Did mitochondria evolved from engulfed prokaryotes?
Yes,they were evolved from bacteria.They were aerobic bacteria.
What is the origin of chloroplasts?
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion. Eukaryotic cells containing mitochondria then engulfed photosynthetic prokaryotes, which evolved to become specialized chloroplast organelles.
Compare and contrast prokayotes and eukaryotes?
Prokaryotes are older, more basic in function and shape, do not contain a true nucleus or any membrane-bound organelles, unicellular (for the most part - some bacteria have multicellular stages in their life), and consist of bacteria and archae (old bacteria). Eukaryotes can be uni- or multi-cellular, have a nucleus and membrane-bound organelles, are generally more complex in shape and function, much larger than prokaryotes and evolved later in history. These are just some basic comparisons.
What did Lynn Margulis account for the presence of DNA in Chromatin and Chromosomes?
According to Lynn Margulis the prokaryotic ancestors of these organelles evolved a symbiotic relationship with early eukaryotes, taking up residence with in the eukaryotic cell. Gaby.m

Yes,they were evolved from bacteria.They were aerobic bacteria.
Did the evolution of prokaryotes preceed the evolution of eukaryotes?
Prokaryotes are a lot simpler than eukaryotes so it can be assumed that prokaryotes evolved before eukaryotes.
Did eukaryotes evolved from a symbiosis between a prokaryotes and protocell?
false
What is the origin of chloroplasts?
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion. Eukaryotic cells containing mitochondria then engulfed photosynthetic prokaryotes, which evolved to become specialized chloroplast organelles.
Which is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA
What must be true if prokaryotes evolved in eukaryotes by endosymbiosis?
the ability to absorb other cells gave some prokaryotes a survival advantage ~*apexx*~
What is the difference between prokaryotics and eukaryotics?
Major difference, Prokaryotes have no cell nucleus and eukaryotics do. Prokaryotes have been present before eukaryotes. Eukaryotes are thought to have evolved from prokaryotes throught the process of endosymbiosis.
What does the endosymbiosis theory propose?
The endosymbiosis theory proposes that eukaryotic cells evolved from symbiotic relationships between different prokaryotic organisms. It suggests that organelles such as mitochondria and chloroplasts were once independent prokaryotes that were engulfed by a host cell, eventually forming a mutually beneficial relationship.
