respiration in plant

Most of plants and animal cells respire aerobically, that is, in the presence of oxygen. However, there are certain microbes that respire in the absence of free oxygen. This respiration is called anaerobic respiration. It is also called fermentatio..

Aerobic and Anaerobic Respiration - Most of plants and animal cells respire aerobically, that is, in the presence of oxygen. However, there are certain microbes that respire in the absence of free oxygen. This respiration is called anaerobic re..

Excretion in Plants - In plants, breakdown of substances is much slower than in animals. Hence accumulation of waste is much slower and there are no special organs of excretion. Green plants in darkness or plants that do not contain chlorophyll produce carbon..

Nutrition in Plants - Most plants are autotrophic. They synthesize their own food. The green plants, also called the producers, trap the solar energy and convert it into chemical energy of the food. The biochemical reactions in the body which result in the formation of..

Water is absorbed due to activities going on in roots. Absorption of water occurs with the help of energy in the form of ATP, which is released due to metabolic activities of root cells such as respiration. Absorption takes place against concentration gradient - even when the concen..

Introduction - Every organism, whether its body is unicellular or multicellular, is capable of performing all vital functions such as respiration, ingestion, excretion and reproduction. In multicellular organisms, because of the increase in body size, it is difficult for each cell to effi..

This theory was proposed by H. Lundegardh, who suggested that anions could be transported across the membrane by cytochrome system. Energy is supplied by direct oxidation of respiratory intermediates. Diagrammatic representation of cytochrome pump hypothesis On salt absorption, anions (A - )..

In some plants, the roots undergo modification to perform special functions, such as storage and respiration..
