What can you conclude from these data?
A) Sample 1 is likely from tissue in the middle of the plant because most cells are in interphase. B) Sample 2 is likely from tissue in the middle of the plant because there are fewer cells in telophase than are in prophase C) Sample 2 is likely from tissue in the middle of the plant because fewer cells are in any mitotic stage. D) Sample 1 is likely from tissue in the middle of the plant because fewer cells are in any mitotic stage than in sample 2.
