What is the result of secondary endosymbiosis?

Meanwhile, secondary endosymbiosis results in the formation of three plasma membranes; the second membrane belongs to the first eukaryotic cell and the third membrane belongs to the second eukaryote.

What is the difference between primary and secondary endosymbiosis quizlet?

Primary endosymbiosis involves the engulfment of a bacterium by another free living organism……… Secondary endosymbiosis occurs when the product of primary endosymbiosis is itself engulfed and retained by another free living eukaryote.

What is the difference between primary and secondary endosymbiosis?

Explanation: Primary endosymbiosis occurs when a eukaryotic cell engulfs and absorbs a prokaryotic cell, such as a smaller cell that undergoes photosynthesis (eg. cyanobacteria). Secondary endosymbiosis occurs when a eukaryotic cell engulfs and absorbs another eukaryotic cell.

What happens during 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 protists evolved secondary endosymbiosis?

Scientists speculate that, in a process called endosymbiosis, an ancestral prokaryote engulfed a photosynthetic cyanobacterium that evolved into modern-day chloroplasts. Molecular and morphological evidence suggest that the chlorarachniophyte protists are derived from a secondary endosymbiotic event.

Why is secondary endosymbiosis important?

Secondary endosymbiosis is when a living cell engulfs another eukaryote cell that has already undergone primary endosymbiosis. It has happened often enough that it has led to genetic diversity among the organisms on Earth.

How many membranes are there in secondary endosymbiosis?

three plasma membranes
Secondary endosymbiosis results in the engulfment of an organism that has already performed primary endosymbiosis. Thus, three plasma membranes are formed.

What is tertiary endosymbiosis?

Only the dinoflagellates have undergone tertiary endosymbiosis, which is the engulfment of an alga containing a secondary plastid (Bhattacharya, Yoon, and Hackett 2004).

What evidence supports the idea of secondary endosymbiosis?

Several lines of evidence support that chlorarachniophytes evolved from secondary endosymbiosis. The chloroplasts contained within the green algal endosymbionts are capable of photosynthesis, making chlorarachniophytes photosynthetic. The green algal endosymbiont also exhibits a stunted vestigial nucleus.

What is endosymbiotic theory quizlet?

The Endosymbiotic Theory. States that organelles such as chloroplasts and mitochondria were once free-living prokaryotes which eventually lived symbiotically within larger cells, forming modern day eukaryotes.

Which organelle evolved through the process of endosymbiosis quizlet?

The endosymbiotic theory says that over time the internal cells evolved to become organelles, mitochondria, and chloroplasts within the eukaryotic cells.
