Adcrustation refers to a biological process where a substance grows from within, expanding the entire structure without any surface layers being added. Essentially, growth happens throughout the substance itself. A common example is the growth of fruits, where the increase in size and mass occurs internally as the entire structure expands, rather than by the … Read more
