respiration in plant

1) Animals release water into the atmosphere by respiration in the form of vapours or to soil as fluid excretion. 2) Water returns to the environment after the death and decay of organisms (plants and animals). 3) A large part of water is given back to nature by plants..

Anatomy of the Leaf - Leaf represents an important part of the plant body. It is involved in vital physiological activities such as transpiration, respiration and photosynthesis. Unlike the stem and the root, the leaf is flat and hence, the anatomy of the leaf differs very much ..

Energy Flow - All living beings require a constant supply of energy for the various functions they perform. The energy is obtained from the sun. This energy is introduced into the biosphere by green plants by a process known as photosynthesis. Plants are able to trap this light ..

Constituent of air Approximate percentage by volume Significance Nitrogen 78.1% Dilutes the air, moderates respiration and combustion; essential for plants to produce proteins Oxygen 20.9% Essential for respiration and combustion Carbon d..

P.R. Stout and Dr. Hoagland have proved that mineral nutrients absorbed by the roots are translocated through the xylem vessel. Mineral salts dissolved in water moves up along the xylem vessel to be transported to all the parts of the plant body. Translocation is aided, by transpiration. ..

>Oxygen is present 21% by volume in air. It supports life and combustion. It is added to air by photosynthesis and removed from air by respiration and combustion. Nitrogen is present 78% by volume in air. It is present in proteins, which are essential for life. It is removed from air by l..

Nitrogen forms nearly 78% of the volume of air. Earlier, the useful significance of nitrogen was not known and it was considered to be inactive. At that time, nitrogen was considered important only because it was known to moderate the processes of respiration and combustion, by diluting t..

'The rate of organic matter build up or stored by producers in their bodies per unit time and area is called net primary production (NPP)'. \ GPP - Energy lost by respiration and maintenance = NPP The biochemical formula that describes photosynthesis is,..

Cells of onion peelMulticellular lifeform All living organisms, whether plants or animals, are made up of microscopic units called cells. The cell occupies the same central position in biology as the atom in the physical sciences. All living beings, plants and animals, start the..
