* 3.5 billion years ago the first life arose: prokaryotic bacteria
* 1.5 billion years ago eukaryotic cells arose Therefore, prokaryotes were present on earth for 2 billion years prior to the emergence of eukaryotic life.

Prokaryotes populated Earth for about 1.5 billion years before the evolution of eukaryotic cells, which are more complex. Eukaryotic cells are believed to have evolved around 2 billion years ago through a process called endosymbiosis.

How does endosymbiosis play a role in the evolution of prokaryotes and how are mitochondria important to this evolution?
Endosymbiosis is the theory that explains the origin of eukaryotic cells from prokaryotic organisms. Mitochondria, once free-living bacteria, were engulfed by ancestral eukaryotic cells through endosymbiosis. This process facilitated the development of more complex cellular structures and functions in eukaryotic cells, contributing to their evolution and ultimately leading to the diversity of life we see today.
Are sea urchins eukaryotic or prokaryotic?
Sea urchins are eukaryotic organisms. They have complex cells with a defined nucleus that contains genetic material, as well as membrane-bound organelles such as mitochondria and golgi apparatus.
Are tigers prokaryotic?
No, tigers are not prokaryotic. Prokaryotes are single-celled organisms that lack a distinct nucleus and membrane-bound organelles, whereas tigers are multicellular eukaryotic organisms with complex cell structures.
How does endo symbiosis play a role in the evolution of prokaryotes to eukaryotes and how are mitochondria important to this evolution?
Endosymbiosis is the process where one organism lives inside another. In the evolution of eukaryotes, it is believed that a prokaryotic cell engulfed a smaller prokaryotic cell, forming a symbiotic relationship. This led to the development of organelles like mitochondria. Mitochondria are crucial in eukaryotic evolution because they produce energy for the cell through respiration, allowing for more complex cellular functions to evolve.
What do eukaryotes have that prokaryotes don't?
Membrane-enclosed Organelles
Cells that are larger and more complex than prokaryotes are called?
Eukaryotic
What is the opposite of a prokaryotes cell?
Eukaryotic cells are cells that contain nuclei and have complex structures. Prokaryotes are generally unicellular and lack nuclei.

Differentiate a proharyotic from a eukaryotic cell?
eukaryotes are usually larger. They are more complex, and they have membrane bound organelles, including the nucleas. Prokaryotes have a nucleoid
Do prokaryotic and eukaryotic cells have a cytoskeleton?
The answer is eukaryotic, prokaryotes have a much less complex cell structure.
Are sea urchins eukaryotic or prokaryotic?
Sea urchins are eukaryotic organisms. They have complex cells with a defined nucleus that contains genetic material, as well as membrane-bound organelles such as mitochondria and golgi apparatus.
Why are prokaryotes older then eukaryotes?
Prokaryotes are considered older because they appeared in the fossil record earlier than eukaryotes. It is believed that the simpler structure of prokaryotic cells made them better suited for survival in the early Earth conditions. Eukaryotic cells with their complex internal structures evolved later.
Are tigers prokaryotic?
No, tigers are not prokaryotic. Prokaryotes are single-celled organisms that lack a distinct nucleus and membrane-bound organelles, whereas tigers are multicellular eukaryotic organisms with complex cell structures.
Do prokaryotes or eukaryotes have tight junctions?
Tight junctions are found in eukaryotes, specifically in multicellular organisms to create barriers between cells. Prokaryotes lack complex organelles and structures found in eukaryotic cells, including tight junctions.

How are eukaryotes and prokaryotes the different?
Prokaryotic cells do not have a nucleus and eukaryotic cells do. The main difference to remember is that everything in a eukaryotic cell is much larger and more complex than what would be fouind in a prokaryotic cell. Bacteria is made of prokaryotic cells. Plants and animals are made of eukaryotic cells. In addition to not having a nucleus (the main difference), prokaryotes also have circular DNA while eukaryotes have linear DNA. As such, prokaryotes do not have okazaki fragments formed during DNA replication. Eukaryote genes have introns and exons while prokaryotes do not, and eukaryotes have more "junk" DNA in general.
