Scientists let rice blast fungal infection cells attach to and attempt to penetrate six different polymer sheets for different lengths of time and in varying extracellular osmotic pressures (Figure 22.9). As the number of the sheet increases so does its hardness. Which of the following makes the most sense based on the data? 100- 60- 5 6 0- 72 96 192 240 incubation time (hr) 100 40- 4. 10 12 B extracellular osmotic pressure, MPa Figure 22.9 Penetration as a function of incubation time (A) and extracellular osmotic pressure (B). Numbers 1 to 6 in both panels indicate the substrate, with lower numbers being softer substrates. Percent penetration goes down over time and as substrate hardness increases. If penetration of a substrate occurs at a particular external pressure, this indicates that internal pressure is high enough to allow penetration of the particular substrate. Harder substrates are more easily penetrated when extracellular osmotic pressures are low. The hardest substrate is too difficult for fungal infection cells to penetrate. If penetration of a substrate occurs at a particular internal pressure, this indicates that external pressure is not high enough to prevent penetration of the particular substrate percent penetrations suogRaued ueed
