Unlike their cousin cells, the Prokaryotic cells, Eukaryotic cells bear a nucleus. They are found in animals, plants, fungi and protists. The presence of a nucleus gives these organisms their name, which comes from the Greek ευ (eu), meaning "good/true," and κάρυον (karyon), which means "kernal."
Does that help at all?
Eukaryotes most likely evolved from prokaryotes.
Oxygen Production.
Archaea are one of the three main domains of life, alongside Bacteria and Eukarya. They did not evolve into another group; rather, they represent a distinct lineage that has existed alongside bacteria and eukaryotes for billions of years. While they share a common ancestor with bacteria, Archaea have unique biochemical and genetic traits that differentiate them from both bacteria and eukaryotes. Evolutionarily, they have adapted to thrive in diverse and often extreme environments, showcasing their adaptability and evolutionary significance.
There are two basic types of cells, prokaryotes and eukaryotes. Eukaryotes differ from prokaryotes in a few ways, but the biggest difference is that eukaryotes have a nucleus and prokaryotes don't.
Eukaryotes can be both unicellular and multicellular. Examples of unicellular eukaryotes include protists like amoebas and paramecia. Multicellular eukaryotes include plants, animals, and fungi.
No.
Eukaryotes most likely evolved from prokaryotes.
Prokaryotes evolve rapidly compared to eukaryotes because they have shorter generation times, larger population sizes, and higher mutation rates, allowing for quicker adaptation to changing environments.
Prokaryotes evolved before eukaryotes because they are simpler in structure and function, making them better suited for surviving in early Earth's harsh conditions. Their ability to adapt quickly to changing environments allowed them to thrive and evolve first.
Oxygen Production.
Eukaryotes evolved from a process call endosymbiosis. Endosymbiosis states that eukaryotes started as two separate bacterium. The bigger bacteria engulfed the smaller. This is how the mitochondria is enclosed in the cell. There is evidence of this because the mitochondria has its on cell membrane and contains its own DNA.
Other eukaryotes may eat eukaryotes and some prokaryotes may eat eukaryotes.
They are prokaryotes so did not evolve in the same way as eukaryotes. Bacteria are "simpler" organisms but have a highly complicated structure of their own
eukaryotes
Eukaryotes are believed to have evolved around 2 billion years ago. This major evolutionary event led to the development of cells with a nucleus and other membrane-bound organelles, marking a significant step in the evolution of complex life forms.
No, animals are eukaryotes.
No, many eukaryotes are microscopic.
