What is rhizosphere effect?
Basically, the rhizosphere effect is a grouping of soil properties that change when in the effective vicinity of roots. Some of these effects are increased number of organisms (mostly bacteria and fungi) and decomposition rates.

What does the word rhizodeposits mean?
The rhizosphere contains many bacteria that obtain nutrients (proteins and sugars released by the roots)and food from sloughed off plant cells (rhizodepositation).
What is the difference between the rhizosphere and rhizoplane?
--"it is a plant root" not really A rhizoid is a "root-like" structure found on non-vascular plants like mosses and liverworts. A rhizome is the bundle of stems that is partially underground and the roots form on in a vascular seedless plant like a fern. A rhizome absorbs water and minerals by producing rhizoids, which are unicellular hair-like structures grown off the rhizome, which absorb these.
Role of rhizosphere microflora in environment microbiology?
The term "Rhizosphere" was introduced in 1904 by the German scientist L. Hiltner to denote the region of soil, which is under the influence of plant roots.Rhizosphere is defined as the region of the soil immediately surrounding the roots of a plant together with the root surfaces.Plant roots receive between 30-60% of the net photosynthesized carbon. Of this, an estimated 40-90% enters the soil as a wide variety of materials including alcohols, ethylene, sugars, amino acids and organic acids, vitamins, nucleotides, polysaccharides, and enzymes. These materials create a unique environment for soil microorganisms, called the rhizosphere. The plant root surface, termed rhizoplane, also provides a unique environment for microorganisms, as these gaseous, soluble, and particulate materials move from the plant plant to soil.The rhizosphere effect is beneficial to the plants in two ways, firstly it helps in providing nutrients to the plants and secondly, it helps the plants in combating root diseases;Here, soil environment may be aerobic or anaerobic. And here Bacteria predominate rather than fungi.Mainly soil bacteria present:Achromobacter, Pseudomonas, Bacillus, Clostridium etc.Fungi such as: Aspergillus flavus, A. niger, Cladosporium herburum, Fusarium oxysporum, and F. solani.Rhizosphere microorganisms are directly associate with root system, i.e, no vector is needed.- Tathagata Bhattacharjee.student of M.Sc -1st year,B.R.S.N College,West Bengal State University.

What is plant exudation?
Root exudates are a range of chemicals mainly Carbon-containing (such as suagrs) released by roots. Thier role is largely unknown. Roots exudates are thought to serve roles as chemical attractants and repellants in the rhizosphere (area of soil that surrounds the root). Alternatively, above ground exudates are released in response to mechanical damage or wounding.

Why are bacteria important to the plant?
Bacteria associated with the plant rhizosphere may have beneficial effects on plant growth by providing nutrients and growth factors, or by producing antibiotics and siderophores, which antagonize phytopathogenic fungi and bacteria. There is considerable experimental support for the idea that plant growth promoting bacteria may be used as bio-fertilizers or biological disease control agents to increase agricultural yields. Recent advances in our understanding of the molecular biology of the systems responsible for plant growth stimulation are opening the way to strain improvement by genetic engineering.
