Figure 5.
(A) Progression of volume density of lysosomes (VvLYS) in the digestive cells of midgut gland tubules of Littorina littorea. Means (symbols) and standard errors (bars) are shown. Different letter codes between single values of the same time point indicate statistically significant differences (p < 0.05); (B) Course of integrity loss of digestive cells (DCI) in the midgut gland tubular epithelium, expressed in arbitrary units (a.u.) (see Table 1 in the Materials and Methods section for explanation). Means (symbols) and standard errors (bars) are shown. Different letter codes between single values of the same time point indicate statistically significant differences (p < 0.05).
