Characterization of the different forms of cell death. a) Different forms of cell death as defined by different terminal cell morphologies. Two predominant forms are type I (rounded shape, red arrows) and type II (elongated shape, green arrows). Type I-rounded cells have shorter lifespan (b), more severely damaged mitochondria (as reported by the Leu4-GFP marker) (c), and higher stress levels (reported by the HSP104 promoter activity) (d), relative to type II-elongated cells.
