After a number of years of teaching, I have used notes which, I feel, can be compiled into condensed and precise note book as a point of reference of those I have taught and those others that would want to benefit from the notes. Cell being the fundamental unit of life need to be well understood by all students taking life sciences. It is for this reason I wish to avail my notes for publication so that, they can be easily be shared by all leaners and scholars. This book can be used as precise learner’s pocket notes. It will serve as a first level entry to studying Cell Biology. This will give the necessary preparation in understanding my other notes in Molecular Cell Biology and Cellular Bio-Engineering. The book will be a good prescription, option to other authors, to all students taking life sciences including Biology, Agriculture, Medicine, Pharmacy, Veterinary among others.
