What do prokaryotic and eukaryotic cells both have in common?
Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. The plasma membrane, or cell membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.
How does endosymbiosis relate to prokaryotes and eukaryotes?
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes. Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission. Mitochondria and chloroplasts have their own DNA which is circular, not linear.
What are two things that support the endosymbiotic theory?
There is much evidence to support the endosymbiotic theory.
- Both prokaryotes and chloroplasts/mitochondria have circular DNA.
- Both have their own ribosomes.
- Both divide through binary fission (splitting into two)
- Both have their own cell membranes.
What supports the endosymbiotic theory?
Explanation: Bacteria, a prokaryote, has circular DNA, as do mitochondria and chloroplasts. This provides support for the Endosymbiotic Theory, which states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote).
How are prokaryotic and eukaryotic cells alike and different?
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.
How are prokaryotic and eukaryotic cells similar and different quizlet?
How are prokaryotic and eukaryotic cells similar? They both have DNA, cytoplasm, ribosomes, and a cell membrane. How is the EVOLUTIONARY AGE (how old they are) of prokaryotic and eukaryotic cells different? Prokaryotic cells are more primitive while eukaryotic cells are more evolved.
What evidence supports the endosymbiotic theory in regard to the origins of eukaryotic organisms that can undergo photosynthesis?
Explanation: Both mitochondria (the organelle that produces energy) and chloroplast (photosynthetic machinery) have their own circular DNA. (The DNA molecules present in the nucleus of eukaryotic cells are in the form of strings and are not circular.)
What is the evidence Scientist have to support endosymbiosis and the evolution of prokaryotes to eukaryotes?
The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.
What is the name of the theory that explains how prokaryotes evolved to eukaryotes?
endosymbiotic theory
Their evolution is explained by endosymbiotic theory. Mitochondria and chloroplasts evolved from prokaryotic organisms. Eukaryotic cells would go on to evolve into the diversity of eukaryotes we know today.
What is the first evidence that supports the endosymbiotic theory?
Single stranded, circular DNA is found exclusively in prokaryotes. This evidence supports the endosymbiosis theory because these characteristics would allow the mitochondria and chloroplasts to survive on their own.
What evidence supports the theory that eukaryotes evolved from prokaryotic cells?
What is the endosymbiotic theory?
Q. Theory that says eukaryotic cells formed from symbiosis among several different prokaryotes. Which of the following are evidence for the endosymbiotic theory.
Are mitochondria prokaryotic or eukaryotic?
Mitochondria and chloroplasts have their own DNA, which is similar to prokaryotic DNA. All eukaryotic cells have a double-layered membran composed of phosplipids and proteins. Fossil evidence shows that the first forms of life were prokaryotic cells.
Are mitochondria and chloroplast descendants of ancient prokaryotic organisms?
On the basis of their relative autonomy and morphological resemblance to bacteria, it was suggested long ago that mitochondria and chloroplast were descendants of ancient prokaryotic organisms. The theory postulate that an aerobic bacteria established residency within the cytoplasm of a primitive eukaryotic cell.
