“The next stage to the simple cytode-forms of the Monera in the genealogy of mankind (and all other animals) is the simple cell, or the most rudimentary form of the cell which we find living independently to-day as the Amoeba.”
“The first and lower stage is the cytode, which consists merely of a particle of plasson, or quite simple plasm.”
“These two parts must have been formed by differentiation from the indifferent plasson of a moneron, or a cytode.”
“By this important differentiation of the plasson into nucleus and cell-body, the organised cell was evolved from the structureless cytode, the nucleated from the unnucleated plastid.”
