I. Read the text and say what information it carries.
THE PHYSICAL BASIS OF LIFE
The realization that all animals and plants possess a fundamentally similar
organization – the structural and physiological units, or cells – leads quite
naturally to an intensive study of the material of which the cells are composed –
the physical basis of life itself. Accordingly we must now consider more
specifically the characteristics of actual life – stuff – protoplasm.
As the finer structure of animals and plants came within the range of vision
through improvements in microscope lenses, it was gradually recognized that
the ultimate living part appeared to be a granular, viscid fluid. This started a
long series of studies on the materials of the bodies of unicellular organisms
similar to Amoebae and of the cellular elements of higher animals and plants,
which finally led, about middle of the last century, to the complete
demonstration of the full morphological and physiological significance of
protoplasm. There s, in truth, an essentially similar, fundamental, living material
