What is an eukaryote?
Q: What is an eukaryote?
A: An eukaryote is an organism with complex cells, or a single cell with complex structures. In these cells the genetic material is organized into chromosomes in the cell nucleus. Animals, plants, algae and fungi are all examples of eukaryotes.
Q: How do eukaryotes differ from prokaryotes?
A: Prokaryotes are simpler organisms such as bacteria and archaea that do not have nuclei and other complex cell structures. Eukaryotes have more complex cells with nuclei and other cellular structures.
Q: When did eukaryotes evolve?
A: Eukaryotes evolved in the Proterozoic era which was around 2 billion years ago.
Q: What is Grypania?
A: Grypania is believed to be the oldest known probable eukaryote which was a coiled, unbranched filament up to 30 mm long found near Negaunee, Michigan about 1.874 billion years ago.
Q: What are acritarchs?
A: Acritarchs are believed to be cysts or reproductive stages of algal plankton found about 1.4 billion years ago in the Mesoproterozoic era.
Q: Does DNA exist in eukaroytes?
A: Yes, DNA exists in eukaroytes as they are organisms that carry it within their cells.
Q: How many kingdoms does modern classification of Euakryota propose?
A: The modern versions of classification for Euakryota disagree on how many kingdoms there should be but generally agree that there should be multiple kingdoms within this domain of organisms
