The rhizosphere is the thin area of soil immediately surrounding the root system. It is a densely populated area in which the roots compete with invading root systems of neighboring plant species for space, water, and mineral nutrients as well as form positive and negative relationships with soil-borne microorganisms such as bacteria, fungi and insects.
Root mucilage is made of plant-specific polysaccharides or long chains of sugar molecules. [1] [2] This polysaccharide secretion of root exudate forms a gelatinous substance that sticks to the caps of roots. [3] Root mucilage is known to play a role in forming relationships with soil-dwelling life forms.
A sundew with a leaf bent around a fly trapped by mucilage. Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms.These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage.

Plant seeds exudate a variety of molecules into the spermosphere, [13] and roots exudate into the rhizosphere; these exudates include acids, sugars, polysaccharides and ectoenzymes, and collectively account for 40% of root carbon. [14] Exudation of these compounds has various benefits to the plant and to the microorganisms of the rhizosphere ...
The seeds are burs, and are very sticky. The plant is native but a well-known nuisance in deciduous forests of the eastern U.S. because the seeds can be difficult to remove from clothing and especially pet fur. [8] [9] The seeding part of the plant—the upper stem—dies earlier than most other plants, and becomes very brittle. Often the ...

Myoporum viscosum is a shrub which sometimes grows to 2 metres (7 ft) in height with young branches that are flattened and sticky. The leaves are arranged alternately and mostly 20–52 millimetres (0.8–2 in) long, 7–20 millimetres (0.3–0.8 in) wide, thick and stiff.
Gary Knight told News9, "It’s a real hero type thing when you see an officer spring into action – save someone's life with the help of a citizen." Fox News’ Michael Dorgan, Maria Lencki ...
