In some plants, the pith in the middle of the stem may dry out and disintegrate, resulting in a hollow stem. A few plants, such as walnuts, have distinctive chambered pith with numerous short cavities (see image at middle right). The cells in the peripheral parts of the pith may, in some plants, develop to be different from cells in the rest of ...
Sholapith or shola pith (also referred to as shola and Indian cork) is a dried milky-white spongey plant matter from Aeschynomene species. It can be pressed and shaped into objects of art, or for practical use. [1] It is the "pith" used for pith helmets, so giving them their name.
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 ...
This tissue system is present between the dermal tissue and forms the main bulk of the plant body. Parenchyma cells have thin primary walls and usually remain alive after they become mature. Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex , pericycle , pith , and medullary rays in primary stem ...
Such ducts may be seen, for example, in various parts of the plant of the carrot family (Umbelliferae). Laticifers are cells or systems of cells containing latex, a milky or clear, colored or colorless liquid. Latex occurs under pressure and exudes from the plant when the latter is cut.
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.

That work saved about 200 Braunton’s milkvetch plants — almost all of which have now likely been torched in the wildfires that consumed Topanga Canyon, along with nearly 24,000 acres (37 ...
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.
