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.
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 ...
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 ...
This image shows the development of a normal plant. It resembles the different growth processes for a leaf, a stem, etc. On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate.

Patterns of xylem development: xylem in brown; arrows show direction of development from protoxylem to metaxylem. Xylem development can be described by four terms: centrarch, exarch, endarch and mesarch. As it develops in young plants, its nature changes from protoxylem to metaxylem (i.e. from first xylem to after xylem). The patterns in which ...
