It is a semi-fluid ground substance enclosed by the plasma membrane. It appears granular due to the presence of large number (as many as 20,000) ribosomes. The ribosomes may occur singly or in clusters called polyribosomes. Membrane -bound cell organelles like mitochondria, lysosomes, golgi complex..

Aromatic compounds containing two or more benzene rings, condensed with each other, are known as multicyclic aromatic compounds or polynuclear aromatic compounds. Some typical examples of polynuclear aromatic compounds are, ..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the environment as ammonia (ammonification), eit..

1) Percolation and ground water recharge has decreased. 2) Floods and drought have become more frequent. 3) Soil erosion has increased. 4) Pattern of rainfall has changed. 5) Land slides and avalanches are on the increase. 6) Climate has become warmer in the deforested region due to lack..

It is the amount of water vapour present in the atmosphere. It can be measured by an Hygrometer. Humidity is greatly affected by intensity of solar radiation, temperature, altitude, wind exposure, cover and water status of soil. High temperatures increases the capacity of air to retain mo..

Minerals are absorbed from the soil along with water as they are dissolved in water. They are taken up in the ionic form . For example, potassium is taken up as K + ions. They are transported through the xylem along with the water. Some of the mineral ions like the nitrates enter into ..

Deficiency Symptoms Of Elements - The absence or deficiency (not present in the required amount) of any of the essential elements leads to deficiency symptoms. The symptoms develop as hunger signs in the plants and can be studied by hydroponics or water culture or soil-less culture. In hy..

Components of the Ecosystem - The environment in which the man and other organisms live is called the biosphere. The biosphere is made up of different regions that have different types of flora (plants) and fauna (animals). The types of organisms in an area are determined by various factors such as..

Both cations and anions have a tendency to get adsorbed on the surfaces of the cell walls, and exchange with ions present in the soil solution. This process of exchange between the adsorbed ions and ions in solution is known as ion exchange. Mineral elements can be absorbed in the form of..
