respiration in plant

Respiration is an important process in nature. It is a process by which the solar energy trapped by the plants in the food can be utilised. The organic compounds are broken down to release energy. This energy is in the form of ATP molecules and is made available for all the vita..

Carbon dioxide is present in the Earth's atmosphere to an extent of 0.03% by volume. Carbon dioxide is produced during combustion of fossil fuels, respiration of humans, animals and plants, fermentation and volcanic eruptions. ..

a) Oxygen in the atmosphere is in a state of 'dynamic equilibrium'. Plants and animals take in oxygen for respiration. b) During respiration, oxidation of carbohydrates and other fuels form carbon dioxide and water. Thus, during respiration oxygen enters the..

Ecological Adaptations - Halophytes - The plants, which grow in saline habitats, are called Halophytes. There is high concentration of salts like sodium chloride, MgSO 4 etc. in these habitats. As the habitat is physiologically dry due to salts, the halophytes show characters similar to X..

At a given low concentration of CO 2 and non-limiting light intensity, the photosynthetic rate of a given plant will be equal to the total amount of respiration. The atmospheric concentration of CO 2 at which photosynthesis just compensates for respiration is r..

It occurs in plants like the yeast (a fungus). It can be represented as follows:..

Compensation Point - At a given low concentration of CO 2 and non-limiting light intensity, the photosynthetic rate of a given plant will be equal to the total amount of respiration. The atmospheric concentration of CO 2 at which photosynthesis just compensates for respirat..

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 terrest..

. Without the constant supply of water the plant cannot carry on any of its physiological activities such as photosynthesis, respiration and growth. Obviously an understanding of the manner in which plants get water is important. In this chapter we shall study the abso..
