This important relationship is known to affect 94% of land plants, [11] and benefits plants by increasing water and nutrient uptake from the soil, particularly phosphorus. In return, the fungi receive food in the form of carbohydrates from the plant in the form of broken-down root mucilage. Without this relationship, many plants would struggle ...
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.
Guttation is the exudation of drops of xylem and phloem sap on the tips or edges of leaves of some vascular plants, such as grasses, and also a number of fungi. Ancient Latin gutta means "a drop of fluid", whence modern botany formed the word guttation to designate that a plant exudes drops of fluid onto the outer surface of the plant, when the ...
Plant exudates include saps, gums, latex, and resin. Sometimes nectar is considered an exudate. [12] 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.

Galium aparine is known by a variety of common names in English. They include ' 'sweetheart', 'hitchhikers, cleavers, [2] clivers, bedstraw, (small) goosegrass (not to be confused with other plants known as goosegrass), [2] catchweed, [2] stickyweed, sticky bob, [3] stickybud, stickyback, sticky molly, robin-run-the-hedge, sticky willy, [2] [4] sticky willow, stickyjack, stickeljack, grip ...
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.

“The history of 12-step came out of white, middle-class, Protestant people who want to be respectable,” said historian Nancy Campbell, a professor at Rensselaer Polytechnic Institute. “It offers a form of community and a form of belonging that is predicated upon you wanting to be normal, you wanting to be respectable, you wanting to have ...
Plants which are heterozygous on the waxy gene (Wx:wx) can be characterised by staining the pollen with iodine. Half of the pollen will be blue and half brown whereas the kernels will stay blue (very helpful in backcrossing program). If the plant is homozygous recessive (wx:wx) the whole pollen will be brown and the kernel too.
