rhizozhere is region of soil around the roots of the plants

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.

--"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.
