Who invented cell?

The discovery of the cell is credited to Robert Hooke, an English scientist, who, in 1665, observed a thin slice of cork under a microscope and described it as being made up of little boxes or cells. The term "cell" was coined by him, and it became widely used to describe the basic unit of life.

NCERT Questions - Fundamental Unit of Life

The cell is the fundamental unit of life, and it is the building block of all organisms. The NCERT textbook for Class 9 Science provides a detailed explanation of the cell and its structure. It is essential to understand the different parts of a cell and their functions to comprehend how living organisms work.

Cell Structure

The cell is a small, complex structure that consists of several components. The cell membrane is the outermost layer that separates the inside of the cell from its surroundings. The cytoplasm is the jelly-like substance that fills the cell, and the nucleus is the control center of the cell.

Types of Cells

There are two types of cells: prokaryotic and eukaryotic. Prokaryotic cells are simple cells that lack a nucleus, while eukaryotic cells have a well-defined nucleus. Bacteria are an example of prokaryotic cells, while plants and animals are examples of eukaryotic cells.

Cell Organelles

The cell has several organelles that carry out specific functions. These organelles include mitochondria, which produce energy for the cell; ribosomes, which synthesize proteins; and lysosomes, which break down waste materials.

Cell Division

The cell divides into two during a process called cell division. There are two types of cell division: mitosis and meiosis. Mitosis is a type of cell division that produces two identical daughter cells, while meiosis is a type of cell division that produces four genetically diverse daughter cells.

In conclusion, the cell is the fundamental unit of life, and it is responsible for the functioning of all living organisms. Understanding the structure and function of the cell is essential to comprehend how living organisms work.
