respiration in plant

(and hence photosynthesis) are in our daily use. Examples: Natural fibres, drugs, vitamins, gums, tannins, turpentine, furniture, etc. Oxygen is being constantly consumed and carbon dioxide evolved by the respiration of animals and plants and by the burning of wood, coal, petrol..

Jan Baptista van Helmont discovered the presence of carbon dioxide in the year 1630. Although the percentage of carbon dioxide in air is very small, it plays a vital role in nature. All the food that is produced on the earth is by photosynthesis, which employs carbon dioxide as the basic raw materi..

During photosynthesis, carbon dioxide is converted into carbohydrates and this is called fixing of carbon dioxide. Many processes like respiration, combustion, volcanic activity, etc. release carbon dioxide into the atmosphere. This carbon dioxide of the atmosphere is used by the te..

Ten Percent Law - Lindemann (1942) put forth ten percent law for the transfer of energy from one trophic level to the next. According to the law, during the transfer of organic food from one trophic level to the next, only about ten percent of the organic matter is stored as flesh. The remaining is..

Before interference by any human activities green house effect by a coverage of gaseous blanket was in close equilibrium with earth's surface in the form of equilibria of carbon, oxygen and hydrogen cycles. Contribution of CO 2 by natural decay of plants and animals or by respiration..

It occurs in plants like the yeast (a fungus). It can be represented as follows: Glucose 2 ethanol + 2CO 2 + 2ATP This process also takes place in higher plants for a very short while and only when free oxygen is not available. For example, germinating seeds respire..

The energy rich carbon compounds formed during photosynthesis- called photosynthates or photoassimilates are transported to all the organs and tissues of the plant body. This long distance transport of photosynthates through the phloem is called as translocation. The photosynthates provi..

The rate of photosynthesis is not constant throughout the day. It's rate is affected by the intensity of light. The actual requirement of the light intensity for maximum photosynthesis in a plant depends on the type of plant and also on its habitat. Generally, average sunlight ..

Photorespiration is also defined as the respiration initiated in the chloroplasts, in the presence of light only. The main features are: The carbon lost is not retrieved. The plant may lose as much as half of the CO 2 fixed during photosynthesis by this process. No energy ..

Green house is usually a type of glasshouse used for raising tender plants. Air inside the green house is usually warmer than the outside, though it receives less solar radiation due to the carbon dioxide present inside, produced by plants (by respiration). This is cal..
