It was Mr. Robert Remak who discoved that new cells are formed from the pre –existing cells. Later on Mr. Rudolf Virchow was the first to accept Mr. Robert’s concept of cell theory and their emergence. Remak found this theory when he was observing red blood cells (RBCs) in the embryo of chicken at all stages of division.
The cell theory is given by Theodor Schwann, Matthias Schleiden, and Rudolph Virchow.
Further explanation:
Cells are the smallest unit of life. It is an essential matter of living. It can be eukaryotic and prokaryotic cells. Eukaryotic cells have a nucleus (DNA) packed within the nucleus membrane, whereas prokaryotic cells have circular DNA, which is called a nucleoid. Cells are consisting of cell organelles that help in performing all the cellular activity.
The cell theory defines the basic theory of life that all the living things are formed from the smallest unit called a cell. This theory is proposed by Theodor Schwann, Matthias Schleiden, and Rudolph Virchow. It explains that the cells are formed from pre-existing cells, not from spontaneous generation.
The modern cell theory explains that energy is formed within the cell. The mitochondria, also are known as the powerhouse of the cell, helps in the formation of energy in the form ATP (Adenosine Triphosphate). It also explains that cell is the medium through which hereditary information is transformed from one generation to another generation. The nucleus of the cell contains DNA (Deoxyriboses nucleic acid) that carries genetic characteristics. All the cells, either eukaryotic or prokaryotic, have the same chemical composition.
