Question

researchers have used several pieces of evidence to support the theory of endosymbiosis. which characteristic of mitochondria and/or chloroplasts present in modern cells is one of these pieces of evidence? when taken out of cells, individual mitochondria and chloroplasts cannot survive on their own. both mitochondria and chloroplasts have their own dna that encodes some of the proteins used by the organelles to carry out their biological functions. chloroplasts are found only in plant cells and algae, while mitochondria are found in all eukaryotes. both mitochondria and chloroplasts function in energy metabolism in the cell. you can respond once

Explanation:

The endosymbiosis theory posits that mitochondria and chloroplasts were once independent prokaryotes that were engulfed by larger cells. Evidence includes them having their own DNA (which can encode some proteins for their functions), their specific distribution (chloroplasts in plant - cells and algae, mitochondria in all eukaryotes), and their role in energy metabolism. The fact that they cannot survive outside the cell also supports the idea that they became symbiotic. All of these points are evidence for endosymbiosis.

Answer:

All of the above statements (When taken out of cells, individual mitochondria and chloroplasts cannot survive on their own; Both mitochondria and chloroplasts have their own DNA that encodes some of the proteins used by the organelles to carry out their biological functions; Chloroplasts are found only in plant cells and algae, while mitochondria are found in all eukaryotes; Both mitochondria and chloroplasts function in energy metabolism in the cell) are pieces of evidence that support the theory of endosymbiosis.
