Cell theory, prokaryotic and eukaryotic cells

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 […]

A living organism is made up of cells and tissues. Both are structurally present and equally important in all living organisms. Cells are a necessary component of tissues; without them, there would be no problems, and cells make up the various types of tissues found in all multicellular creatures. Every living thing has at least

Introduction to Cell: The Unit of Life The most fundamental, structural, and functional unit of all living beings is the cell. A cell is a structure containing organelles that perform essential processes to survive. Not all cells, though, are the same. Plants and animals have cells that are substantially different. The absence of cell walls

For new cells to grow, the old cells need to die, replaced by the new and healthy cells. When there is an abnormal growth of cells, it hampers the organ or any part of the body as the cells’ growth rate is more than required. Carcinoma means cancer which is the most common type of

The primary distinction between Euchromatin and Heterochromatin is that Euchromatin is an uncoiled packed form of chromatin that is genetically active. While heterochromatin is a tightly packed version of the chromosomes that is genetically inactive. Under a light microscope, the non-dividing cells of the nucleus are divided into two zones based on the concentration or

Every living thing is composed of cells, which are the smallest units of that living creature. Organism is the term used to refer to a living thing that is made up of one cell (such as bacteria) or many cells (such as a human). The basic building blocks of all organisms are, therefore, cells. The

The immune system defends the body against worms, bacteria, and other harmful substances. The immune system resembles a castle from the Middle Ages. A moat and lofty stone walls surrounded the fortress on all sides. Soldiers stood poised within the castle to fight off any invaders who managed to get past the outside fortifications. The

Despite its simplicity, the bacterium has a well-developed cell structure that contributes to its distinct biological features and pathogenicity. Many structural properties of bacteria are found nowhere else in archaea or eukaryotes. The cell structure of bacteria has been widely investigated, revealing many biochemical concepts that have since been applied to other creatures, due to

Introduction Today, bacteria cells are measured as one of the oldest styles of life on earth. Even supposing most bacteria build made humans sick, they need a semi-permanent, mutual relationship with humans greatly necessary for our survival.  Bacteria Definition “Bacteria single cellular organisms relating to the prokaryotic cluster wherever the organisms lack a couple of

Microorganisms are tiny organisms that are microscopic in size. They can be divided into five major groups- bacteria, algae, fungi, archaea, protozoan, and viruses.  Bacteria are unicellular organisms that belong to the prokaryotic category. Their size ranges between 1 and 10 micrometres. They reproduce by a process called binary fission.  Bacteria are known to be
