Die Zelle und die Gewebe (Vol. 2/2)

The work presents a systematic survey of tissue anatomy and physiology, centering the cell as the fundamental unit. It examines levels of biological individuality from solitary cells to multicellular assemblies, discussing colonies, syncytia, and differentiated cellular associations, and explores symbiosis, parasitism, and cell-to-cell communication including protoplasmic bridges and surface contacts. The text considers developmental and physiological integration, factors shaping tissue formation, theories of development and inheritance, and the causal principles underlying organization, combining experimental observations, histological evidence, and theoretical analysis across twenty-one chapters.
