Who discovered the cell and how? Go
The cell is the basic structure of all living things. The human body is made up of trillions of cells. It gives shape to our body and produces energy by getting nutrients from food. Genetic substances such as DNA are also present inside the cell. But do you know, first of all Koshika ki khoj kisne ki and when? So the answer is - Robert Hooke. It was he who discovered the cell in 1665.
Robert Hooke was a natural philosopher from England. In 1665, when he looked at the thin pieces of cork of the bottle under a compound microscope, he saw thousands of tiny holes in them.
He named those small holes 'Cell'. The word cell is derived from the Latin word 'cella', which means a small room.
However, Hooke did not know the actual structure or function of those holes. the pores he believed to be cells; They were actually empty cell walls of plant tissue.
Due to the lack of a good microscope at that time, they could not see the other important components present inside the cell, peek inside the cell wall.
In later years, other scientists of the world made many discoveries about the cell and its actual structure. Other important questions and answers related to cell are given below. Also read these-
Q2. Do cells commit suicide too?
Answer: Yes! Cells also commit suicide. When cells are damaged due to external or internal reasons, they protect the whole body by destroying themselves. The process of cells destroying themselves in this way is called apoptosis.
The cells made to perform a particular function in the body become unnecessary after the work is over, so their destruction is good for the body.
Cells whose DNA is damaged due to some reason, they die on their own. That is, commit suicide. If such bad cells survive and continue to divide, then they can also turn into cancer cells.
Similarly, when the virus divides from our cell and prepares to spread the disease, then suddenly our sick cells containing the virus die. Along with this, viruses are also eliminated. In this way the body is protected from disease.
Q3. Robert Hooke discovered a dead cell, but do you know who is credited with discovering a living cell?
Answer: The living cell was discovered by the Dutch scientist Antoine van Leeuwenhoek in 1674. He is also credited with the discovery of protozoa, bacteria and the sperm cell.
Q4. Who gave the cell theory?
Answer: The cell theory was propounded by Theodor Schwann and Matthias Jakob Schleiden in 1838.
Q5. Who discovered the mitochondria that produce energy inside the cell?
Answer: Mitochondria were discovered by Albert von Kolliker in 1857.
Q6. What is the study of cells called?
Answer: The study of the cell is called cytology. Under this science, the structure and function of the cell is studied.
Q7. What is the name of the smallest cell in the world?
Answer: Mycoplasma is the smallest cell in the world. Its size is about 10 micrometers. The smallest cell in the human body is the sperm cell.
Q8. Which is considered the largest cell in the world?
Answer: The largest cell in the world is considered to be the egg of an ostrich bird. The largest cell in the human body is considered to be the ovum.
Q9. What are the main types of cells?
Answer: There are mainly two types of cells-
Prokaryotic Cell: It is a cell in which the nucleus is not found in the middle. Organisms having this type of cell are very small in size. e.g. different types of bacteria
Prokaryotic Cell: The nucleus is found in the center of this cell. These types of cells are larger in size than the nucleolar cell and their structure is also complex. These types of cells are found in humans and plants.
Q10. How are tissues made?
Answer: Tissues are made up of a group of cells of the same type.
Q11. In whose cell is the cell wall found?
Answer: In plant cells
Q12. Which type of cell was the first to develop on Earth?
Answer: Prokaryotic cell
Q13. What is the function of the ribosome in the cell?
Answer: Protein synthesis
Q14. What is the main function of the nucleus in the cell?
Answer: Controlling cell growth and reproduction
Q15. How do cells reproduce?
Answer: Most prokaryotic cells reproduce by binary phagocytosis and eukaryotic cells by sexual or asexual process.
Q16. How many cells do we have in our body?
Answer: Scientists estimate that there are about 75 to 100 trillion cells in the human body.
