What does the cell theory state, which is considered one of the most important discoveries in the history of modern biology, and which changed the view of biologists about the formation of bodies and living organisms, and reached the final form of this scientific theory, with consistent studies of accurate studies and microscopic facts about body parts and through our article In this we will learn with you what the cell theory states, in addition to getting acquainted with the interpretation of the cell theory, in addition to getting to know what the cell components and their functions are.
When was the cell discovered?
The cell was discovered for the first time by the scientist Robert Hooke in 1665, when the invention of the microscope was still recent, and he conducted his experiments on a piece of cork under the microscope lens, then he noticed the so-called box-like structures that served as the basis for the development of the classical cell theory. In the year 1838, Theodor Schwann and Matthias Schleiden deduced the first two parts of the content of the cell theory known today, and after the research conducted by Rudolf Virchow on some plants and animals in 1858, the third part of the content of the cell theory known today was discovered.
What does the cell theory say?
The classic cell theory is considered one of the most important theories in modern biology, the facts of which were obtained after analyzing the particles of living organisms under a microscope. The text of the cell theory was divided into three parts as follows:
- The bodies of all living things are made up of cells which can be one or more cells.
- The cell is the basic unit and the main functional component of life.
- That the cell consists of other cells already present in the body, similar in structure and function.
Interpretation of the cell theory
All living things in our world are made up of cells, whether their bodies are made up of one cell or more than one cell. Here is a comprehensive explanation of the cell theory:
- Cells are formed after a process of reproduction called cell division.
- One cell is the basic structural unit and functional unit of all living things.
- The activity of an organism is generated by the sum of the activities of the autonomous cells in its body.
- Energy flow is the result of metabolism and biochemistry within the cellular structure.
- Cells contain mobile DNA in the chromosome, in addition to RNA in the cell nucleus and cytoplasm, which are the materials responsible for transmitting hereditary traits.
- Similar types of cells take on the same chemical composition in the bodies of living organisms.
What are the components of a cell and their functions?
Cells are usually formed and reproduced by the process of cell division, so that the new cells contain the basic genetic material found in the primary cells from which they separated.
With this amount of information, we have come to the end of our scientific topic, where we got acquainted with the reasons for the cellular theory, and the scientific and accurate interpretation of the articles of the cellular theory, where we got to know the answer to the question posed about what the cell theory states, in addition to knowing what the components of the cell are and their functions.
