|
|
|
a large cell engulfed and digested a smaller cell, exposing its enzymes for use by the larger cell.
|
|
|
two cells merged into one cell, improving the enzyme function of the new cell.
|
|
|
two cells were juxtaposed and one benefited from the other.
|
|
|
a small cell lived inside a larger cell to the benefit of both cells.

Detailed explanation-1: -Question: The endosymbiosis hypothesis proposes that a small cell lived inside a larger cell to the benefit of both cells. two separate cells worked cooperatively and one benefited from the other. a large cell engulfed and digested a smaller cell, exposing its enzymes for use by the larger cell.
Detailed explanation-2: -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.
Detailed explanation-3: -According to the endosymbiosis theory, the host cell engulfed the bacterium, and instead of digesting it as food, it negotiated a functional relationship that enabled the host cell/endosymbiont to utilize oxygen in energy metabolism.
Detailed explanation-4: -Cell Systems Endosymbionts are organisms that form a symbiotic relationship with another cell or organism. Some endosymbionts can be found either inside cells (intracellular), while others attach to the surface of cells (extracellular). Symbiotic relationships are ones in which both parties benefit.
Detailed explanation-5: -Eventually, the smaller prokaryotes that had been engulfed adapted and evolved into some of the organelles we know of today in eukaryotic cells such as the mitochondria and chloroplasts.
