drag the labels to the appropriate locations in this diagram. first drag pink labels to pink targets to label the two host cells. then drag blue labels to blue targets to label the structures and endosymbionts of the two cells.

The endosymbiotic theory states that an ancestor cell phagocyted photosynthetic and oxygen-consumer prokaryotes, and originated eukaryotic cells with mitochondria and chloroplasts. a) Oxygen-using prokaryote, b) Mitochondrion, c) Nucleus, d) Endoplasmic reticulum, e) Host cell: Ancestor of all eukaryotes, f) Photosynthetic prokaryote, g) Chloroplast, h) Host cell: Ancestor of photosynthetic eukaryotes

What is the endosymbiotic theory?

The endosymbiotic theory proposes that mitochondria and chloroplasts were once free-living bacteria that were phagocytized by another cell but not digested. These bacteria got to adapt to their host, and both cells became interdependent.

Both organelles have many similarities with other free-living bacteria.

Chloroplasts probably derivate from cyanobacteria because both cells absorb sunlight, and produce ATP, and organic molecules.

Mitochondria derivate from rickettsias because they produce ATP in the same way by using the Krebs Cycle and Oxidative Phosphorylation.

Chloroplasts and mitochondria share some traits with free-living bacteria, that support the theory.

Both organelles present their genetic material. This DNI is independent of the cell's DNA, is bi-catenary and circular, identical to the bacterial DNA, and very different from the one of the eukaryotic cells.

Both organelles divide by binary fission, not by mitosis, and can synthesize their ribosomes and organelles.

Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the bacterial membrane, while the external membrane looks like the eukaryotic one.

In fact, in this internal membrane are placed the energy centers, just as occurs in bacterias membrane.

Finally, the sizes of the organelles are similar to the size of some procaryotes.
