Discovery and Origin Endoplasmic reticulum (also called ergastoplasm) was discovered by Porter et al. (1945) and the term ER was given by Porter (1953). According to different views, ER originates either from invagination of the plasma membrane or fro…

Lysosome are important cellular organelles commonly known as “suicide bags” or “disposal units” of the cell. They play a crucial role in intracellular digestion and cellular defense mechanisms. Discovery and Structure Lysosomes were discovered by Chr…

TMV (Tobacco Mosaic virus) is a plant virus which infects a wide range of plants. TMV causes disease of Tobacco, Tomato and other members of the family Solanaceae. TMV belongs to Tobamovirus group. TMV is first virus ever discovered by Iwanowski i…

Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are the most important molecules in biology, responsible for the storage of genetic information that underpins all life. They are both linear polymers, consisting of Penrose sugars, phosphates a…

Apoptosis, also called "programmed cell death" is the process where the cell regulates its own death through the production of certain enzymes. These enzymes cause degradation of nuclear and cytoplasmic material and the cell breaks into fr…

Cell cycle is one of the most breathtaking processes that helps the cells to not only grow but also divide. Cell cycle has two major phases : Interphase , which helps in the preparation of the cells for the division. M( Mitosis / Meiosis ) phase, thi…

Small molecules like hormones can act as messengers, interacting with receptors in the plasma membrane or or within the cell, that then amplify the signal or activate and carry out some cellular functions. As it happens, many of these signals regul…

When the organisms are allowed to grow in a nutrient environment, the concentration of solutes in the cell is usually much higher than the concentration of solutes in the extracellular environment.   Moreover, the composition of Intracellular solute…

Every living creature on earth begins as a single cell. That cell undergoes mitosis , dividing over and over again, with certain cells becoming specialized, until eventually. cell division begins with an existing cell. Instead, that first cell came …

Mitosis is a part of cell cycle, which mean the cells copy the genome and grow in preparation for cell division. The actual process of cell division is called mitosis, is happening all over your body right now, and it’s quite complex. Mitosis is div…

Blood is a body fluid in humans and animals that transport necessary substance such as nutrients and oxygen to the cells or tissues and remove metabolic waste products (carbon dioxide) away from those same cells. Blood contains 7-8% volume of Body…
