Absorption of Water by Plants - Plants absorb water through the entire surface - roots, stems and leaves. However, mainly the water is absorbed by roots. The area of young roots where most absorption takes place is the root hair zone. The root hairs are delicate struct..

. Turgidity of guard cells is regulated by K + fluxes between them and the surrounding epidermal cells. Transpiration is also influenced by environmental factors such as light, temperature, availability of soil water and atmospheric humidity. Transpiration facilitates the movement of water and mine..

Some water is present in the form of hydrated oxides of aluminium, iron, silicon inside the soil. This is also a non-available form of water for plant roots. Diagram Showing Different forms of Soil Water and their Possible Relationship with Soil and Plant Water Status Seedling S..

It is the movement of water between aquatic systems, air and land water vapour condenses to form clouds, and eventually rainfall. Plants play an important role in this cycle by the process of transpiration. The upper limit (maximum) of water availability of a soil is called field capac..

Contamination of radioactive substances such as wastes of uranium and thorium can be carried into water from nuclear power plants, during their mining and refining processes. Scientific and medical institutions, which utilize radioactive materials can also contaminate water bodies. These..

Major Ecosystems (Biomes) - Biome is a large, regional or sub continental biosystem characterized by a major vegetation type or other distinct landscape characters such as tropical deciduous forest, tundra biome, etc. "The major terrestrial ecosystems (largest ecological units) of distinctive terre..

The space between soil particles on the surface of earth is called pore space. It is of two types - micro and macro pores. Most of the water is held in micro pores. Pores, which are available for plant roots. Surface soil pore spaces are generally filled with air and water. Wate..

Construction of sound proof rooms for noisy machines in industries. Use of horns with jarring sounds to be banned. Noise producing industries, aerodromes, and railway stations to be shifted away from the inhabited areas. Proper law should be enforced to check the misuse of loudspeakers a..

). It makes use of spaced-based remote sensing data along with socio-economic data. Some important remote sensing applications are listed below: (1) In Geology: Geology has a long history of remote sensing applications. The existing, geological maps have been updated. (2) In Agriculture: ..

Earth is the only planet on which life exists. It consists of three components Lithosphere (Land), Hydrosphere (Water) and Atmosphere (Air). Life originated and evolved because of this unique combination of the three components and was ideal and favourable for life. The life supporting zon..
