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.
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.
Parenchyma is a versatile ground tissue that generally constitutes the "filler" tissue in soft parts of plants. It forms, among other things, the cortex (outer region) and pith (central region) of stems, the cortex of roots, the mesophyll of leaves, the pulp of fruits, and the endosperm of seeds.
Pith – the spongy tissue at the center of a stem. Chambered pith – a form of pith in which the parenchyma collapses or is torn during development, leaving the sclerenchyma plates to alternate with hollow zones; Diaphragmed pith – pith in which plates or nests of sclerenchyma may be interspersed with the parenchyma.
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.
A multicellular, glandular hair that usually produces a mucilaginous substance and is located on sepal s, stipules, or petioles, or on nearby parts of stem s; commonly found on plants in the order Gentianales. columella In flowering plants, the central axis of the cone or fruit, e.g. in Callitris. column 1.
