Cell theory asserts the unity of all living things and their evolutionary development f engels called cell theory one of the three greatest discoveries the discovery of the cell and the development of cell theory do not coincide historically the english microscopist r hooke was the first to observe. Simply put, modern cell theory says that all organisms alive on the earth are made up of cells all life consists of one or more cells, and new cells form modern cell theory isn't all that modern when you understand how long ago it originated with roots in the mid-17th century, multiple scientific scholars.
Technology such as lenses, magnifying glasses, and microscopes had an impact on the development of the cell theory below are some examples of how such technologies contributed to the cell theory robert hooke is accredited with observing the first cells in 1665 at that time, robert hooke used a. The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells the concept was formally articulated in 1839 by schleiden & schwann and has remained as the foundation of modern biology the idea predates other great paradigms of. The modern cell theory, one of the fundamental generalizations of biology, holds that new cells come from pre‐existing cells lifeforms today have descended in unbroken continuity from the first primitive cells that arose on earth more than 35 billion years ago.
Cell theory definition is - a theory in biology that includes one or both of the statements that the cell is the fundamental structural and functional unit of living matter and that the organism is composed of autonomous cells with its properties being the sum of those of its cells. Explain how the advance in technology allowed the progressive accumulation of knowledge and understanding of the cell theory the technological notably, prior to the proposal of the cell theory, limited knowledge and understanding of what humans comprised of was evident and thus the theory.
Cell theory was actually a generalization of observations made by many scientists around the world cell theory was proposed by theodor schwann, matthias schleiden and modern cell theory some more points are added with the advancement of our knowledge in cytology and molecular biology.

Cellular theory defined classical cell theory, first proposed by matthias schleiden and theodor schwann, consisted of three primary points cell structures under the microscope the microscope was improved and modified for better observation of different cells and microscopic organisms. Cell theory refers to the idea that cells are the basic unit of structure in every living thing development of this theory during the mid 17th century was made the theory says that new cells are formed from other existing cells, and that the cell is a fundamental unit of structure, function and organization in all. Cell theory is one of the basic principles of biology given by the german scientists theodor schwann, matthias schleiden, and rudolph virchow it allowed the post-renaissance biologists to look at their specimen in greater detail, and eventually come up with the cell theory.
Asses impact of technology on cell theory technology has had a profound impact on the development of cell theory, allowing scientists to view the components of organisms on an unprecedentedly small scale before the creation of microscopes, misconceptions about how. Cell theory the theory that was born of the findings of matthias schleiden  in 1838 and theodor schwann  in 1839, who postulated, respectively, that plants and animals cell theory a dictionary of biology © a dictionary of biology 2004, originally published by oxford university press 2004. 1 what is the basic building uint 2 animals 3 bird 4 plants 5 all living things have different sizes, and shapes 6 what is the basic building unit that all living.
