Create a 20 page essay paper that discusses The Human Cell.
The researcher states that the chemical processes and complex interactions that occur inside the cell form the bridge between the nonliving and the living. Inside the human body, various processes that go on synchronized to provide efficient healthy functioning are interrelated and coupled for optimum functional output. This requires the organization at various levels. In complex living beings like humans, there are many levels of an organization, as opposed to single cellular organisms like bacteria. The study about the cell and its structure were revolutionized with the invention of the microscope. The discovery of microscope in 16th century encouraged scientists to study these basic building blocks. It was Robert Hooke who discovered the cell in 1965 and named it Cellulae (Latin: tiny rooms) as he observed box-like structures in a thin slice of cork under his microscope. He was the first one to describe the fungus Mucor. Later Antony Van Leeuwenhoek improved the microscope and documented some initial findings of protozoa and bacteria. The contributions of Matthias Schleiden, Theodor Schwann, and Rudolf Virchow lead to the development of ‘The Cell Theory’ in 1839. According to the cell theory: 1. All living things are made from one or more cells. 2. The cell is the basic unit of life. 3. All cells come from preexisting cells. Advances in microscopy and imaging led to further research into the cell structure. It is now an established fact that cells are composed of various organelles and there are complex signaling pathways that control the expression of various molecules. The structure and composition of different cell types vary, but certain characteristics are common to all cells. Cells of the similar kind together form the tissues. There are four basic types of tissues that form the entire organism, epithelium, supporting or connective tissue, muscle and nerve tissue. Organs are formed by two or more tissue types combined together for a specific function.
