Penicillium is a genus of fungi that are saprophytic (that is, they feed on dead and rotting matter). They are also referred to as green or blue mould. They are essential for the production of cheese, organic acids, and antibiotics, all of which are valuable commodities. They are a major decomposer in the environment and […]

Discovery of abscisic acid Abscisic acid was first isolated from cotton plants and was initially named Abscisin 2. In the same year, two scientists, Eagles and Wareing (1963), isolated an active substance of maple leaves and called it dormin. Abscisin 2 and dormin are the same substance which is now called abscisic acid. Abscisic acid

Dormancy is a stage in an organism’s life cycle during which growth, development, and (in the case of animals) physical activity are temporarily slowed or suspended. This reduces metabolic activity and, as a result, aids an organism in its efforts to conserve energy. Dormancy is often found to be closely associated with specific environmental conditions,

Introduction  Understanding the diversity in the living world from the perspective of taxonomy is important to understand the classification, properties, features, attributes of the living organisms on the planet. The concept of diversity in the living world is helpful for better understanding organisms and their life processes.  Biological Classification All living organisms are broadly categorised

When the temperature drops, certain creatures enter a dormant state and hibernate. Diapause, on the other hand, is a dormant state most commonly observed in insects in which the insect’s growth is temporarily halted. Several species go dormant in order to survive periodic adversities such as environmental changes, food scarcity, temperature fluctuations, and so on.

The definition of respiration in plants tells us that it is usually a process in which the plants use atmospheric oxygen for oxidising glucose and other respiratory substrates like proteins, fats, etc. The respiratory substrates are usually the organic nutrients that are oxidised at the time of respiration.  These substrates are normally high-energy biomolecules that

Introduction Cellular respiration is the process by which plants and animals’ cells break down sugar and convert it to energy. Cellular respiration has a simple goal: it provides energy to cells so they can function. Organisms mix oxygen with food molecules, channelling the chemical energy in these molecules to life-sustaining processes while discarding carbon dioxide

What is Glycolysis? Glycolysis converts glucose into energy in the form of NADH, ATP and Pyruvate. In the presence or absence of oxygen, the site of glycolysis in a cell is in the cytosol of a cell’s cytoplasm. The first stage in cellular respiration is glycolysis. In the absence of oxygen, cells use the fermentation
