What is Breathing?

Q. What is breathing? Ans. Breathing is an external process, in this process inhale of air and exhale of air. Or  Breathing (or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide.   Breathing is also known as external respiration. It is part of respiration but not internal or cellular respiration. The process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and whose gaseous composition differs markedly from that of the ambient air . Physiological respiration involves the mechanisms that ensure that the composition ...

Reproduction By Conidia


 Reproduction by Conidia:

o   These are non-motile spores produced endogenously by constriction at the tips of special hyphal branches known as conidiophores.
o   Asexual reproduction in ascomycetes (the phylum Ascomycota) is the formation of conidia, which are borne on specialized stalks called conidiophores.
o   The morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (e.g. Metarhizium) species.

What is Respiration?

Q. What is Respiration? Definition : Respiration is the process by which chemical energy stored in the food is released in the form of ATP along with carbon dioxide and water. Whole the process completed inside the cell. It is also known as "cellular respiration". OR  Oxidation of food with the help of inhaled oxygen and released energy is called Respiration , it always occurs at cellular level (inside the cell). Respiration completed in two step: i. Breathing (External Respiration) : Inhale of air and exhale of air is called Breathing. Breathing is not respiration, it is part of respiration. Without breathing respiration cannot be done. ii. Metabolism (internal Respiration) Cellular Respiration : It is the process which involves exchange of oxygen and carbon dioxide between  the organisms and the environment.

what is Binary Fission? How many types of Binary Fission?

                           Asexual reproductions are following types: A.    Fission B.    Budding C.    Spore formation D.    Fragmentation E.    Regeneration F.    Gemmulation G.    Conidia formation H.    Zoospores I.     Vegetative propagation A.   Fission (Fission=division) It is type of Asexual reproduction in which a fully-grown parent cell divides into two or more than two daughter cells. In this, the reproductive unit is whole parental body. Types of Fission: On the basis of number of off-springs produced, fission reproduction is divides into two categories:   (a)       Binary Fissio n Definition: I t is division of adult parental body into two nearly equal daughter cells during favorable condition. Occurrence: It is the simplest and mos...
