What is the process of endosymbiosis?

What is the process of endosymbiosis?

Endosymbiosis involves one cell engulfing another to produce, over time, a coevolved relationship in which neither cell could survive alone. The chloroplasts of red and green algae, for instance, are derived from the engulfment of a photosynthetic cyanobacterium by an ancestral prokaryote.

What are 2 examples of endosymbiosis?

Termites and their protozoan gut inhabitants are one example of the endosymbiont living within a cavity of the associate organism. Another common example is the fauna in the stomach of ruminating animals, or animals that regurgitate and rechew food particles, such as deer, cattle, and antelope.

Which is the best explanation for endosymbiosis?

A symbiotic relationship where one organism lives inside the other is known as endosymbiosis. Primary endosymbiosis refers to the original internalization of prokaryotes by an ancestral eukaryotic cell, resulting in the formation of the mitochondria and chloroplasts.

What is endosymbiosis and why is it important?

1 Answer. Endosymbiosis is important because it is a theory that explains the origin of chloroplast and mitochondria. It is also a theory that explains how eukaryotic cells came to be.

Can chloroplasts self replicate?

Chloroplasts contain their own genetic material as DNA and ribosomes. The plastid DNA possess genes which produce the proteins necessary for the functioning of plastids. They can self-replicate and form more copies of them.

What is true endosymbiosis?

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 do you mean by cyanobacteria?

Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see.

What are the 4 types of Type 1 symbiosis?

There are five main symbiotic relationships: mutualism, commensalism, predation, parasitism, and competition.

What is the Endomembrane theory?

The endomembrane system (endo- = “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins.

What are the two basic types of cells?

There are two distinct types of cells: prokaryotic cells and eukaryotic cells.
