Figure 2

SMS cross-sections at 17 DAYS. Scale bar: 100 μm. Parameter values were those listed in Table 2. White circles: proliferating CELLS; light gray circles: quiescent CELLS; dark gray circles: NECROTIC CELLS. The background gradient (from red to black) represents NUTRIENT levels relative to the maximum value in red. (A) Growth occurred at high NUTRIENT, which maps to 0.28 mM oxygen and 16.5 mM glucose. (B) Growth occurred at low NUTRIENT, which maps to 0.08 mM oxygen and 0.8 mM glucose.
