The Mechanism of Life The cell theory was for some time combated by the most eminent German men of science. A History of the Nineteenth Century, Year by Year Volume Two (of Three) It is in no other way conceivable that Virchow should contemn the most important consequences of the cell theory as "mere trifling with words." Freedom in Science and Teaching. from the German of Ernst Haeckel The contemporaneous study of development brought out the same result; and the zoologists and botanists, exploring the simplest and the lowest forms of animated beings, confirmed the great induction of the cell theory.

Life and Letters of Thomas Henry Huxley — Volume 1 All physiology, then, properly interpreted, becomes merely a study of cellular activities; and the development of the cell theory takes its place as the great central generalization in physiology of the nineteenth century. A History of Science — Volume 4 We now see very clearly how extremely important the cell theory has been for our whole conception of organic nature. The Evolution of Man — Volume 1 Hence, the establishment of the cell theory, in normal biology, was swiftly followed by a "cellular pathology," as its logical counterpart. Science & Education Apart from the cell theory, man is an insoluble enigma to us. The Evolution of Man — Volume 1 But this attempt was bound to miscarry, since its not very clear-headed author lacked a sound acquaintance with embryology and the cell theory, and even with the structure and development of the tissue in particular. The Evolution of Man — Volume 1 The important circumstance that this mammal ovum is a simple cell, like the ovum of other animals, could not, of course, be recognised until the cell theory was established. The Evolution of Man — Volume 1 In reality, the term "cell," which existed long before the cell theory was formulated, is not happily chosen. The Evolution of Man — Volume 1 Without going any further here into these very interesting phenomena of the life of the cell, we will pass on to consider the application of the cell theory to the ovum.
