An interesting approach to the internal microenvironment of the eukaryotic cell. The recent information in terms of the morphological and functional characteristics of the cell is blended with the accepted classical information written in the previous books.Original pictures obtained by using light and electron microscope and figures drawn by the author herself are fascinating. The author is discussing about the conflicting data on morphological and functional aspects of the cells and adding her own opinions based on her knowledge derived from being a experienced researcher on Histology and Embryology and a writer of various books on Histology and Embryology. As a scientist and poet, this book of the writer is readable as a long but exciting poem.
