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.
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 must be true if prokaryotes evolved into eukaryotes by absorbing?
If prokaryotes evolved into eukaryotes by absorbing other prokaryotic cells, it must be true that the engulfed cells retained some functional capacity, allowing them to contribute to the metabolic processes of the host cell. This endosymbiotic theory suggests that these absorbed cells eventually became organelles, such as mitochondria and chloroplasts, through a symbiotic relationship. Additionally, genetic material from the engulfed cells would need to be integrated into the host's genome or maintained separately, facilitating cooperation and communication between the host and its symbionts.
Is eubacterium a type of Eukaryotic?
Yes
Did the evolution of prokaryotes preceed the evolution of eukaryotes?
Yes, prokaryotes are believed to have evolved before eukaryotes. Eukaryotes likely evolved through a process of endosymbiosis, where prokaryotic cells engulfed other prokaryotic cells to form a symbiotic relationship, leading to the development of cellular organelles.
What evolved from prokaryotes?
Eukaryotic cells evolved from prokaryotes.

What must be true if prokaryotes evolved in eukaryotes by endosymbiosis?
If prokaryotes evolved in eukaryotes by endosymbiosis, then the prokaryotes must have provided a benefit to the host cell that allowed them to coexist and eventually evolve together. Additionally, evidence of this evolutionary event would likely include the presence of organelles in eukaryotic cells, such as mitochondria and chloroplasts, which have their own DNA and replicate independently from the host cell.
What did eukaryotes most evolve from?
Eukaryotes most likely evolved from prokaryotes.
Why are eukaryotes classified as separate from prokaryotes when eukaryotes are made up colonies of prokaryotes?
Actually, eukaryotes are NOT made up of colonies of prokaryotes. They are separate, individual (mostly multicellular) organism. That's why they're classified as separate from prokaryotes, because they're different. Eukaryotic cells have a central nucleus While prokaryotes don't Also the eukaryotic cell divide differently than prokaryotic cells. They also have some difference in the number or types of organelles in the cells

Kingdom in which all prokaryotes are placed?
Prokaryotes are placed in the kingdom Monera, which includes bacteria and archaea. These organisms lack a true nucleus and membrane-bound organelles, distinguishing them from eukaryotes. However, the classification of prokaryotes has evolved, and some taxonomists now recognize bacteria and archaea as separate domains rather than grouping them together in one kingdom.
Did eukaryotes evolved from a symbiosis between a prokaryotes and protocell?
false
What did Lynn Margulis account for the presence of DNA in Chromatin and Chromosomes?
Lynn Margulis proposed the endosymbiotic theory to explain the presence of DNA in chromatin and chromosomes. This theory suggests that eukaryotic cells, which contain DNA in their mitochondria and chloroplasts, arose from symbiotic relationships between ancient prokaryotic cells.
Which is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA
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.
