A cell biologist treated some cells with a stain. She found that the stain was concentrated within the mitochondria of many types of cells. Which conclusion could the cell biologist draw regarding the results of this test? A.The stain could be used to identify mitochondria in living cells B.The stain could be used to determine if cells were alive or dead. C.All stains will be absorbed by mitochondria. D.All mitochondria create stains.

A

B is wrong because mitochondria would likely absorb the stain even if it was dead.(And most cells that have been treated are dead anyway). C and D are just throwaway answers, you usually want to avoid the word "always" when drawing conclusions.

Answer:

Option (C).

Explanation:

Mitochondria is the semi autonomous cell organelle that acts as the energy house of the cell. Chemical like Janus green B can be used to identify the mitochondria in the cell.

A cell biologist has treated cells with stain that concentrates in the mitochondria. The cell biologist can conclude that the stain can be specifically used to stain the mitochondria as the stain is concentrated in the mitochondria of different cells and the stain is absorbed by the mitochondria.

Thus, the correct answer is option (C).
