Cell Structure and Function

The Kingdom Protista was set up by Ernst Haeckel in 1866. Eukaryotes are the organism which has a nucleus and is surrounded by other membrane-bound organelles. Protists are eukaryotic cells which are neither animal or plant or fungi. Most protists are unicellular but not all of them. Some protists are multicellular as well. This Kingdom […]

The concepts of the cell and that life comes from pre-existing cells were introduced in 1800 by the invention of the microscope.  The classic cell theory was introduced by Theodor Schwann, Rudolf Virchow, and Matthias Schleiden; it mainly consists of three parts.  The first part says all living organisms are made from the basic unit,

Introduction The study of living beings is referred to as biology. Their diversity was highlighted by the comprehensive explanation of their form and looks. The cell theory highlights the unity that lies beneath this diversity of forms, namely the cellular organisation of all living things. Whenever one observes living organisms, the very first question that

Introduction Have you ever wondered what distinguishes a living thing from a non-living thing? The obvious answer is that a living organism has life in it, while a non-living thing does not. A cell, the unit of life, is the basic functional and structural unit in all living organisms. In fact, the cellular organisation is

A cell is the smallest fundamental unit of life, and it is responsible for the survival of the living being. Cells are known as the building blocks of human life.  Robert Hooke was the first biologist who discovered the cell in 1665. When he observed a piece of bottle cork under a microscope, he noticed

Cell theory was first formulated in the 1939. The theory proposed is known as the classical cell theory, and cell as the basic unit of life was its main proposal. This means that the theory proposed some basic concepts which stem from this basic assumption. Later on, the modern cell theory added other concepts to

Every living being is made up of cells. A mass of cytoplasm bound externally by the cell membrane is called a cell. This fundamental is the base of cell theory. Cells are microscopic, and they are the smallest structural unit of all living things. Most of the cells have one or small nuclei and other

The cell membrane, cell walls and outer membrane make up the cell envelope. This envelope is usually a characteristic of bacteria and other prokaryotes. It consists of the cell wall of the bacterium and its inner cell wall. The cell’s cell envelope is responsible for its structural integrity. The cell is protected by the internal

Introduction As we know, every living organism is made up of cells. Thus, the cell acts as both structural and functional units in them. A cell contains several small organelles embedded in them. The cell is microscopic and is easily visible by light microscopes. However, to study the detailed structure of the cell and its
