Briefly summarized, this doctrine states that cells are the fundamental units of both structure and function in all living things; that all forms of life animal, plant, and microbial are composed of cells and their secretions; and that cells arise only from preexisting cells, each cell haying a life of its own in addition to its integrated role in multi-cellular organisms.
This statement seems both elementary and obvious to any student with some background in the biological sciences. Nevertheless, it took several centuries for this concept to be developed and accepted. It finally became apparent that a fundamental similarity existed in the structural organization of all the living things studied.
Francis and Zacharias Janssen, who manufactured eyeglasses in Holland, are generally credited with the construction of the first compound microscopes in Malpighi was among the first to use a microscope to examine and describe thin slices of animal tissues from such organs as the brain, liver, kidney, spleen, lungs, and tongue.
His published works also include descriptions of the development of the chick embryo. Antonie van Leeuwenhoek Dutch, was one of the most distinguished of all the early microscopists. His sketches included numerous bacteria bacilli, cocci, spirilla, etc.
He described the blood cells of mammals, birds, amphibians, and fish, noting that those of fish and amphibians were oval in shape and contained a central body i. Hooke popularized the use of microscopes among contemporary biologists in England and built several compound microscopes of his own.
On one occasion, Hooke examined a thin slice cut from a piece of dried cork. What he observed, of course, were not cork cells but rather the empty spaces left behind after the living portion of the cells had disintegrated.
Nehemiah Grew English,together with Marcello Malpighi, is recognized as one of the founders of plant anatomy. His publications included accounts of the microscopic examination of sections through the flowers, roots, and stems of plants and clearly indicate that he recognized the cellular nature of plant tissue.
Grew was also the first to recognize that flowers are the sexual organs of plants. Purkinje Czech, coined the term protoplasm to describe the contents of cells. Inhe wrote that each cell leads a double life—one independent, pertaining to its own development, and another as an integral part of a plant.
In this century, especially during the past 25 years, we have witnessed an unprecedented growth of our knowledge of the cell, its structural organization and diversity, its chemical organization, and the various functions of its component parts. This understanding is founded on the contributions of many thousands of scientists working in laboratories all over the world.
Many such awards in the fields of chemistry, physiology, and medicine have been made for contributions that bear directly on cell biology see Table A major difference between an Advanced Placement Program (AP) biology course and a regular high school biology course is the emphasis on detail.

AP Biology includes those topics regularly covered in a college biology course. Topics are integrated throughout the course using the eight major themes from the AP Biology Curriculum Requirements. These eight themes are Science as a Process, Evolution, Energy Transfer, Continuity and Change, Relationship of Structure and Function, Regulation.
